Batch Image Editor

Editing forty photos one at a time is forty chances to set something slightly differently. A batch editor turns the settings into a recipe and applies it identically to every file, so a product catalogue, an event gallery or a set of blog images comes out matching — and it takes one pass instead of forty.

Benefits of Batch Editing

• One pass, not forty: the same size, the same look and the same naming across the whole set.
• Consistency you can see: previews update as you adjust, so you know what the batch will look like before it runs.
• Size and colour together: resizing and grading in one step, rather than exporting twice through two tools.
• Names that make sense: a folder of camera numbers becomes a folder of names you chose.
• One download: the finished set arrives as a single archive instead of a queue of save prompts.

Drop a set of photos, build one recipe, and every photo comes out the same way. Nothing is uploaded — the editing happens on your own device.

1. 1Add your photos: Drop JPG, PNG, WebP, GIF or BMP files, or browse for them. Free handles three at a time; Pro takes a hundred.
2. 2Pick a recipe: Start from one of nine — a 1600 px web set, square thumbnails, a cleaner product shot, or one of six looks — then adjust anything underneath.
3. 3Set the size and the names: Choose a long edge or an exact size, and a name pattern if you want the files renumbered as they are saved.
4. 4Apply and download: Press Apply, watch the previews update, then take the files one at a time or the whole batch as a single ZIP.

Most bulk edits start with size. Pick a long edge and every photo lands at that edge with its shape intact, or give an exact width and height and choose whether the extra is trimmed away or left as space. Cropping keeps the most detailed part of the frame rather than the middle, which is the difference between a square thumbnail that shows the subject and one that shows their shoulder.

• Long edge: one number, every photo the same size, portraits and landscapes alike.
• Exact size: a fixed width and height, filled and cropped or fitted inside.
• Percent: half size, quarter size — useful when the originals vary.
• Four resampling filters: Lanczos for photographs, Nearest for pixel art that must stay hard-edged.

A folder of DSC_4417.JPG tells nobody anything. A name pattern rewrites every file as it is saved, with tokens for the original name, a running number, the finished dimensions and today's date. Numbering starts wherever you say, so a second batch can carry on from the first.

• {name} — the original name, without its extension.
• {nnn} — a running number, zero-padded to as many digits as you type.
• {w} and {h} — the finished width and height.
• {date} — today, as YYYY-MM-DD.

Two photos that would end up with the same name are numbered apart instead of overwriting each other, and anything a filesystem would refuse is cleaned out of the name before the archive is built.

Nine starting points cover the usual jobs — a 1600 px WebP set for a website, square thumbnails, a cleaner product shot, and six looks. Each one sets every value it touches, so a recipe produces the same result whatever you had loaded before it. Adjust anything underneath and save the result as your own recipe; it will be waiting the next time you open the page.

Resize, then blur, then sharpen, then colour. It is not a limitation — it is the order that gives a correct answer. Sharpening before a resize sharpens detail that is about to be thrown away; sharpening after a colour grade sharpens the grade's own clipping instead of the picture. Doing the size first also means a blur radius or a sharpening amount means what you see, because it is measured against the pixels you are going to keep.

Your photos are opened on your own device and pushed through a fixed four-stage pipeline: size first, then blur, then sharpening, then colour. Each stage runs on your graphics hardware where it is available and falls back to a slower path that produces the same picture where it is not, so the result does not depend on what machine you are on.

What Happens to Each Photo

• Opened on your device: including the rotation stored by a phone camera, so portraits stay portrait.
• Resized: with the filter you chose, in floating point, so gradients do not band.
• Adjusted: all nine colour stages in a single pass, with no rounding between them.
• Encoded: as PNG, JPEG or WebP, at the quality you set.
• Named and packed: with your pattern, with duplicates numbered apart, into one archive.

Anywhere a set of images has to look like a set.

Every photo is opened, edited and saved on your own device. Nothing is uploaded, so a hundred-photo batch costs no upload time and no waiting behind anyone else's queue, and photos that should not travel — client work, documents, family pictures — do not. The editing itself is hardware accelerated, which is what makes a full folder finish in seconds rather than minutes.

• No upload: the files stay in the tab you opened them in.
• No queue: your machine is the only machine involved.
• Works offline: once the page has loaded, the network is not needed.

• Resize a single image
• Photo filters and curves
• Compress images
• Batch rename files
