Convert Images to PowerPoint

1. 1

   Add your images

   Drop in JPG, PNG, WebP, GIF, BMP, AVIF or SVG files, or click to browse. Everything is read on your device — nothing is uploaded.

2. 2

   Choose the slide size and placement

   Pick a slide size such as 16:9 widescreen or 9:16 portrait, then choose Fit to letterbox each picture, Fill to cover the slide edge to edge, or Stretch to force it to the frame.

3. 3

   Set the layout details

   Choose one, two or four pictures per slide, add captions from the filenames, pick a frame, set the margin and background colour, and turn on a title slide or slide numbers if you want them.

4. 4

   Check the live preview and reorder

   The preview shows the actual slide as it will be written. Drag the thumbnails or use the arrows to change the order, and step through the slides to check every one.

5. 5

   Create the PowerPoint file

   Enter a filename and select Create PowerPoint. The PPTX is built on your device and saved to your downloads, ready to open in PowerPoint, Google Slides, Keynote or LibreOffice.

This free Images to PowerPoint tool builds a PPTX deck from a set of pictures, entirely on your device. Choose from seven slide sizes, place one, two or four pictures per slide, keep proportions with Fit or cover the slide with Fill, add captions and frames, reorder by dragging, and watch a live preview of the actual slide before you download it. It is aimed at the decks people really build from images: marketing boards, training slides, portfolio pages, event recaps and photo albums.

• Seven slide sizes: 16:9 widescreen, 4:3 standard, 1:1 square, 9:16 portrait, 21:9 ultrawide, and the 3:2 and 2:3 photo ratios — all free.
• One, two or four pictures per slide: a full-bleed slide, a side-by-side pair, or a two-by-two grid, matching what PowerPoint's own Photo Album offers.
• Placement: Fit keeps the proportions and letterboxes, Fill covers the slide edge to edge and trims the overflow, Stretch forces the frame.
• Captions and a title slide: captions default to the filename and can be edited per picture; a title slide with a heading and subtitle can lead the deck.
• Frames, background and numbering: white, black, rounded or soft-shadow picture frames, any slide background colour, and optional slide numbers.
• Speaker notes: each slide can carry the filenames of the pictures on it, so you can still tell which original a slide came from later.
• A live preview: drawn from the same measurements used to write the file, so what you see is what the deck contains.
• Reordering: drag the thumbnails, use the arrows, or sort the whole batch by filename in one press.

Start with the slide size, because everything else follows from it. 16:9 is what a projector, a laptop screen and a video call all expect. 4:3 still suits printed handouts and older screens. 1:1 and 9:16 are for social posts, where a square or a full-height portrait frame is the format people scroll. 21:9 suits a wide banner or a panorama. 3:2 and 2:3 match the shape a camera actually produces, so a photo fills them with nothing trimmed and no bars.

Placement then decides what happens when a picture's shape does not match the slide. Fit scales the picture until it sits fully inside and centres it, leaving bars in the slide's background colour — nothing is lost, which is what you want for artwork, screenshots and charts. Fill scales until the picture covers the frame and trims the overflow evenly from both sides, which is what you want for photographs, where filling the slide matters more than keeping the edges. Stretch ignores proportions altogether; it is there for the cases where you know the picture was made for the frame.

The margin controls the breathing space around the grid, and its range follows the rest of your settings rather than being a fixed number. A one-inch margin is generous on a 21:9 slide and would leave almost nothing on a 9:16 one with four pictures on it, so the slider stops where the pictures would stop being usable. Set the margin to zero with Fill and one picture per slide and the photo reaches all four edges exactly; set it to zero with four per slide and the grid has no seams at all.

One picture per slide is the classic slideshow, and it is the default. Two per slide is a comparison — before and after, two options, two angles — and the tool arranges them the way the slide's shape asks for: side by side on a landscape slide, stacked on a portrait one, so neither picture ends up as a sliver. Four per slide is a contact sheet or an album page, always a two-by-two grid.

Captions sit beneath each picture and default to the filename with its extension removed, which is the same default PowerPoint's Photo Album uses and is usually more meaningful than it sounds — exported photos tend to carry dates, product codes or place names. You can type your own caption for any picture instead. Captions are written as ordinary text boxes, so anyone opening the deck can click one and edit it; the text is never burned into the picture.

Frames change how a picture sits on the slide. A white or black border separates a photo from a background of a similar tone. Rounded corners soften a grid of screenshots. A soft shadow lifts a picture off the slide and reads well on a plain background. The caption colour follows the background you choose, switching to a light tone on a dark slide, so a dark deck never gets captions nobody can read.

Not every image format a browser can open is a format PowerPoint can draw, and that difference is the single most common way an image deck ends up broken. A PPTX file carries pictures as ordinary files inside the package, and each program that opens the deck has to decode them itself. JPG, PNG, GIF and BMP are drawn by every version of PowerPoint, by Google Slides, by Keynote and by LibreOffice Impress, so those four go into the deck exactly as you supplied them — no decoding, no re-encoding, no second generation of compression, and no loss.

WebP and AVIF are different. The newest Microsoft 365 builds of PowerPoint render WebP; PowerPoint 2016 and 2019, Google Slides, Keynote and LibreOffice do not, and AVIF support is thinner still. A deck with those pictures dropped straight in downloads perfectly and then shows a broken-picture box on somebody else's machine. This tool converts them on the way in instead — to PNG when the picture has transparency and to JPG when it does not — so the deck you send behaves the same wherever it is opened. SVG is converted the same way, because a vector has no fixed size until something rasterises it.

Accepted

• JPG / JPEG: stored exactly as supplied, with the orientation tag read and applied.
• PNG: stored exactly as supplied, transparency intact.
• GIF: stored as supplied; an animated GIF keeps its animation in a slideshow.
• BMP: stored as supplied.
• WebP: converted to PNG or JPG so older PowerPoint, Google Slides and Keynote can draw it.
• AVIF: converted for the same reason.
• SVG: rasterised at a size that stays sharp on a full slide.

Refused, with somewhere to go

• HEIC / HEIF: the format iPhones use by default — convert it to JPG first, and the deck is unaffected.
• TIFF: no browser decodes it; the converter handles it.
• PSD: a layered document rather than an image.
• PDF: already a document — turn its pages into images first if you want them on slides.
• ICO: an icon container, not a picture.

A photo taken on a phone is very often stored sideways. The camera writes the picture in the sensor's own orientation and records which way up it should be shown in a small tag beside the pixels. Browsers and photo apps read that tag; PowerPoint does not. That is why photos dropped straight into a deck so often appear rotated, and why the file looks perfectly fine until somebody opens it. This tool reads the tag and turns the picture upright before it is embedded, covering all eight orientations — including the four mirrored ones, where rotating alone would leave the photo upright but back to front.

Resolution is the other half of the file-size question. A slide is about thirteen inches wide, so a picture wider than about 4000 pixels contributes nothing a projector or a screen can show — it just makes the deck heavier to open and slower to email. A free deck therefore embeds pictures at up to 4096 pixels on the longest edge, which is more than a 4K display can resolve across a full slide, and Pro embeds at the original size for print work and archives. Pictures already inside the limit are never touched at all.

Because the accepted formats are stored rather than re-compressed, a deck is close to the size of the pictures that went into it — a batch of 54 MB of photos produced a 54.5 MB file in testing, the difference being the slide descriptions themselves. Repeated pictures are written once and referenced from each slide, so a logo on forty slides costs the deck one copy of it, not forty.

A deck is still the fastest way to hand somebody a sequence of pictures that they can present, annotate, reorder and send on. Slides open on every machine in an office, they print, they export to PDF, and they can be edited by the person who receives them — which a folder of photos or a video cannot be. Building that deck by hand means inserting each picture, resizing it, aligning it and repeating, and the alignment is what goes wrong first.

• Event and travel recaps: a hundred photos become an album deck with captions in one pass.
• Product and portfolio boards: a two-by-two grid per slide reads as a catalogue page.
• Training and process documents: one screenshot per slide, captioned with the step's filename.
• Social formats: a 9:16 or 1:1 slide size gives a deck that exports straight to the shape a platform wants.
• Before-and-after comparisons: two pictures per slide, side by side, at identical sizes.
• Handing over assets: speaker notes carry each picture's filename, so the original is always traceable.

Everything happens in the page. When you add pictures the tool reads the first few bytes of each file to identify what it really is — not the file extension, which can be wrong, and not the type the operating system reports, which is often empty. From those bytes it also reads the picture's size and its orientation tag without decoding the image at all, which is why a hundred files appear in the queue immediately rather than after a hundred decodes.

When you select Create PowerPoint, the work moves to a background thread so the page stays responsive: thumbnails still scroll, settings still respond, and the run can be cancelled. Each picture is either copied in unchanged or, if it needs converting, turning upright or scaling down, decoded and re-encoded once. The slide descriptions are written as compressed XML, the pictures are stored without further compression because they are already compressed, and the whole thing is packed into the .pptx you download.

The preview beside the settings is drawn from the same measurements that get written into the file — the same rectangle, the same crop, the same caption box. It is not a rendering of the finished document, and it does not need one, which is why it updates as fast as you can move a control rather than after a rebuild.

Pictures that already suit PowerPoint are copied into the deck untouched, so a 60-slide batch is written in about a fifth of a second on this machine.

• Name the files before you start. Filenames become captions and speaker notes, and sorting by filename is the quickest way to fix the order of a large batch.
• Match the slide size to where it will be shown. 16:9 for a projector or a call, 9:16 or 1:1 for social, 3:2 for photographs you do not want trimmed.
• Use Fill for photographs and Fit for anything with edges. Screenshots, charts and artwork lose meaning when their edges are trimmed; photographs rarely do.
• Set the margin to zero for a full-bleed deck. With Fill and one picture per slide, a zero margin is what reaches all four edges exactly.
• Turn on captions before you reorder, not after. Seeing the filenames on the slides makes a wrong order obvious in the preview.
• Convert HEIC photos first. iPhone photos are HEIC by default and no browser can open them; the converter turns a whole folder into JPG in one pass.
• Split very large batches. Several smaller decks are quicker to build, quicker to open and easier to email than one enormous one.
