Your JPGs and PNGs go in untouched
Most converters decode every photo and re-compress it before writing the PDF, which makes the document larger than the pictures that went into it and costs a second round of lossy compression on top of the one the camera already applied. This tool does not. A JPG that needs no rotating, resizing or recolouring is copied into the PDF exactly as you handed it over, byte for byte, and a PNG is copied the same way with its transparency intact.
The practical difference is large and it is easy to check: open the finished PDF's file size next to the total size of the images you added. Twenty 12-megapixel photos totalling 7.8 MB come out as a 7.85 MB PDF, and every page is the original picture rather than a copy of it.
- Nothing is re-compressed: a photo in the PDF is the same data as the photo on your disk, so it never softens or gains blocky edges.
- Transparency survives: a PNG with a transparent background keeps it, instead of being flattened onto white.
- It is fast because it is not doing anything: with no decoding and no encoding, a twenty-page album is built in milliseconds.
- You can turn it off: choose Smaller file and every page is re-encoded as JPEG at the quality you pick, which is the right trade when you need to email the result.
A page has to be re-encoded whenever you rotate it, convert it to greyscale, lower the resolution, or add a format PDF has no filter for (WebP, GIF, BMP, AVIF and SVG). The queue marks each page so you can see which is which. If the finished document is still bigger than you want, run it through the PDF compressor.
Page size, margins and how the image sits on the page
A PDF page has a fixed size and your images do not, so something has to give. This tool gives you both halves of that decision: what shape the page is, and what the image does inside it.
Page sizes
- Fit to image: each page takes the shape of the image on it, so nothing is letterboxed and no white bars appear. This is the right choice for screenshots, receipts, product shots and anything that is not going to be printed.
- A4: 210 x 297 mm, the standard almost everywhere outside North America.
- Letter: 215.9 x 279.4 mm, the North American standard.
- Legal: 215.9 x 355.6 mm, taller than Letter for contracts and forms.
- A3: 297 x 420 mm, twice A4, for posters and plans.
- A5: 148 x 210 mm, half A4, for booklets and handouts.
How the image fits
- Fit: scaled down until the whole image sits inside the margins. Nothing is cut off and the proportions are kept.
- Fill: scaled up until it covers the page edge to edge. The overflow is trimmed by the page boundary, which is what you want for a full-bleed slide.
- Actual size: placed at the size it would print at, and shrunk only if that will not fit. A 1200 x 1800 pixel photo lands at about 317 x 476 mm before shrinking.
- Stretch: forced to the margins on both axes, ignoring the image's proportions. It distorts, which is occasionally exactly what a background needs.
Image to PDF Conversion Explained
Image to PDF conversion combines multiple images into one document. You can add images in batches, drag to reorder, rotate any image, set page size and orientation, choose image fit (fit, fill, actual size, stretch), adjust JPEG quality, and set a custom output filename. Preview the result before downloading.
Conversion Process
- Upload & Add More: Select images; add more later without clearing the list
- Reorder & Rotate: Drag thumbnails to reorder; use rotate button per image
- Set Options: Page size, orientation, margins, image fit mode, JPEG quality, custom filename
- Convert & Preview:Generate PDF and preview it; convert again if needed
- Download: Download with your chosen filename; file size shown
Which image formats work
The list below is the whole list, and it is enforced when you pick a file rather than after you press the button — so you never watch a progress bar that was always going to fail.
- JPG / JPEG: embedded untouched. Progressive JPEGs and CMYK JPEGs are re-encoded, because PDF's own image filter does not cover them.
- PNG: embedded untouched when it is greyscale, truecolour or palette-based. Interlaced PNGs and PNGs with an alpha channel are re-encoded, losslessly by default.
- WebP: decoded and re-encoded; PDF has no WebP filter.
- GIF: decoded and re-encoded. An animated GIF contributes its first frame, and the queue says so.
- BMP: decoded and re-encoded. Usually much smaller in the PDF than it was on disk.
- AVIF: decoded and re-encoded, where the device can open it.
- SVG: drawn at up to 2048 pixels on its long side, then embedded as a picture.
What is turned away, and where to take it
Three things arrive here often and cannot be opened by any device on its own. Rather than accept them and fail, the tool names the format and sends you to the tool that handles it.
- HEIC and HEIF, which is what an iPhone saves by default — convert HEIC to JPG first
- TIFF, PSD and other editor formats — use the image converter
- another PDF, which is a merge rather than a conversion — use the PDF merger

How Image to PDF Conversion Works
Image to PDF conversion combines multiple images into one PDF with reorder, rotation, fit options, and preview. Understanding the process helps you get the best results.
Conversion Process
- Upload & Order: Add images (and more later). Drag to reorder and rotate any image 90°. Order and rotation define the final PDF pages.
- Page & Fit Settings: Set page size, orientation, and margins. Choose image fit: fit (scale to fit), fill (cover page), actual size, or stretch. Optionally set JPEG quality and custom filename.
- Image Embedding: Each image is processed (with rotation), converted to PDF-compatible format (PNG for transparency, JPEG with your quality otherwise), and placed on a page using the chosen fit mode.
- Preview & Download: The PDF is built and shown in a preview. You can convert again with different settings or download with your custom filename.
- Batch:Add more images and rebuild the PDF without reloading.
Why it finishes so quickly
Two reasons. Pages that need no changes are copied rather than rebuilt, so most conversions do almost no work at all. Pages that do need changing — a rotation, greyscale, a lower resolution — are handled by your device's graphics hardware, and the work happens away from the page so the interface keeps responding and Cancel keeps working. Everything runs on your device; no image is ever sent anywhere.

Limits, and what Pro adds
Every setting on this page is free. Page size, orientation, margins, all four fit modes, greyscale, the compression choices, the resolution choices and all four presets work without an account. What the paid plan changes is scale, not capability.
- Free: up to 150 images in one PDF, up to 50 MB each, embedded at up to 4096 pixels on the long side.
- Pro: up to 500 images in one PDF, with no imposed size cap — the ceiling is what your own device can hold.
- Pro, print-ready: images are embedded at their full resolution, which matters when the PDF is going to a printer rather than to a screen.
- Pro, document details: a title and an author written into the PDF's properties, so the reader's title bar shows something better than the filename.

Frequently Asked Questions
How does image to PDF conversion work?
Image to PDF conversion combines multiple images into a single PDF. You upload images, optionally reorder them by drag-and-drop and rotate any image 90°, then set page size, orientation, margins, and image fit mode (fit, fill, actual size, or stretch).
What image formats are supported?
Our converter supports JPG, JPEG, PNG, GIF, WEBP, BMP, and other common image formats. PNG images with transparency are embedded as PNG in the PDF; others use JPEG with adjustable quality. You can mix formats in one PDF.
Can I reorder and rotate images before converting?
Yes. Drag thumbnails to change page order, and use the rotate button on each image to turn it 90° clockwise. You can also move images up or down with the arrow buttons. Order and rotation are applied when you click Convert to PDF.
What are the image fit options?
You can choose Fit (scale to fit inside the page), Fill (scale to cover the page, cropping if needed), Actual size (no scaling, fit to page if too large), or Stretch (fill page ignoring aspect ratio). These apply to all pages in the PDF.
Can I combine multiple images into one PDF?
Yes. Upload all images, optionally add more later, arrange order by dragging, set your options, and convert. Each image becomes one page. You can convert again with different settings without re-uploading.
Will image quality be preserved?
Yes. You can set JPEG quality (slider) for non-transparent images; transparent images are embedded as PNG. Fit mode and page size control how images are scaled. Preview the PDF before downloading to check quality.
Is my image data secure?
Yes. No data is stored or transmitted, so your files stay private and secure.
Can I customize PDF page size, orientation, and filename?
Yes. Set page size (A4, Letter, Legal, A3), orientation (Portrait or Landscape), and margins. You can also set a custom output filename (e.g. report.pdf) and preview the PDF before download.
How many images can I convert at once?
You can convert many images at once; limits depend on device memory and file sizes. You can add more images after the first batch without clearing. For very large sets, converting in batches may perform better.
Does converting to PDF reduce my image quality?
Not by default. A JPG or PNG that needs no rotating, resizing or recolouring is written into the PDF exactly as you supplied it, so there is no second round of compression and no visible change at all. Quality is only re-encoded when you ask for something that requires it — a rotation, greyscale, a lower resolution, or the Smaller file setting.
Why is my PDF the same size as my photos?
Because it contains the same data. A PDF is a container, and the pictures inside it are your original files rather than copies. A little overhead is added for the page structure, which is why a 7.8 MB set of photos becomes roughly a 7.85 MB document.
Can I convert HEIC photos from my iPhone?
Not directly — no browser can decode HEIC on its own, so the tool refuses the file rather than accepting it and failing later. Convert the photos to JPG with the HEIC converter first, then bring them back here. Setting your iPhone camera to Most Compatible saves JPGs instead of HEIC in the first place.
Will a photo taken sideways come out sideways?
No. A photo from a phone carries an orientation tag rather than being stored the way it looks, and the tool reads that tag itself and turns the picture upright before placing it. The queue says so on any image where it applied, and you can still rotate any page by hand on top of that.
How do I make the PDF as small as possible?
Choose Smaller file, drop the JPEG quality to around 70 percent, and set the resolution to 150 DPI — or 96 DPI if it will only ever be read on a screen. Greyscale takes roughly another third off for scans and text documents. The estimated output size beside the button updates as you change each of these.
Can I put a page in landscape and the next one in portrait?
Yes. Set Orientation to Auto and each page turns to match its own image, so a mixed folder of landscape and portrait shots comes out with no letterboxing on either. Fit to image goes further and gives every page the exact shape of the picture on it.
