Add images to get started
JPG, PNG, WebP, BMP, GIF or AVIF · up to 200 files · max 30 MB each
BMP, GIF and AVIF are read and come back as JPG, PNG or WebP. Animated files are not accepted — a canvas only ever sees the first frame.
How to crop images in bulk
- Add your images. Drop up to 200 JPG, PNG, WebP, BMP, GIF or AVIF files onto the box above, or choose them from your computer. They stay on your machine.
- Pick a ratio. Each row shows the outline of what will be kept and the exact size the result will be, before you crop anything.
- Crop and download. Take the images one at a time, or download the whole batch as a ZIP.
The five ratios, and where they are used
- Square — 1:1 — Instagram posts, avatars, product grids and thumbnails.
- Landscape — 4:3 — The classic camera and print shape, and most slide decks.
- Widescreen — 16:9 — Video thumbnails, page headers and hero banners.
- Portrait — 3:4 — Pinterest, printed portraits and tall product shots.
- Vertical — 9:16 — Stories, Reels, TikTok and any full-screen phone image.
What a centre crop does, and what it does not
For each image the tool takes the largest rectangle of your chosen ratio that fits inside it and positions that rectangle in the middle. A 1600×1200 photo cropped to 1:1 keeps the middle 1200×1200 and discards 200 pixels from each side. Nothing is stretched, nothing is scaled, and no bars are added.
That is deliberately predictable rather than clever: the same rule applies to every file in the batch, so a hundred photographs come out the same shape without a hundred decisions. It is also why the crop only ever removes pixels — the result is a piece of your original at its original resolution, not a resampled copy of it. If you need every image at one exact pixel size as well, crop first and then run the results through the bulk image resizer.
The trade-off is worth knowing: a centre crop assumes the subject is near the middle. For product shots, headshots and most photography it is, which is what makes cropping a whole batch in one pass reasonable at all. When it is not — a subject deliberately placed off to one side — that image is better cropped on its own.
Formats and transparency
Every image comes out in the format it went in as. That is not a limitation but the point: cropping is a change of shape, and quietly turning a PNG into a JPG while doing it would throw away transparency nobody agreed to lose. A transparent PNG or WebP keeps its alpha channel through the crop. If you do want a different format, the bulk image converter does that on its own.
An image that is already the ratio you asked for is handed straight back untouched, rather than being re-encoded to produce an identical picture with slightly worse quality.
Why crop in the browser?
Taking a rectangle out of an image is arithmetic on pixels your computer already has. Sending a file to a server to have that done, then sending it back, is slower for a large batch, costs someone money per image, and puts your files on a machine you do not control. Doing it locally is the reason this tool has no sign-up and no usage limit.
Frequently asked questions
- Are my images uploaded anywhere?
- No. Cropping happens in your browser using the canvas API. Your images never leave your computer, which is why the tool needs no account and has no usage limit.
- Where is the crop taken from?
- The centre. For each image the tool keeps the largest rectangle of the ratio you chose that fits inside it, positioned in the middle, and trims what hangs over. That is the same rule for every image in the batch, which is the point of cropping in bulk — a hundred product photos come out the same shape without a hundred decisions.
- Are my images resized as well as cropped?
- No. The pixels that survive the crop are kept at their original resolution, so a 1600x1200 photo cropped to 1:1 comes out 1200x1200 rather than being scaled to some other square. If you also need everything at one exact size, run the results through the bulk image resizer afterwards.
- What happens to an image that is already the right shape?
- Nothing at all. The tool hands back the original file untouched rather than re-encoding it, so a square image cropped to 1:1 loses no quality and no bytes.
- Does cropping a transparent PNG keep the transparency?
- Yes. The output format is always the format you started with, so a PNG stays a PNG and its alpha channel comes through the crop intact. The same is true of transparent WebP.
- How many images can I crop at once?
- Up to 200 per batch. They are processed a few at a time rather than all at once, so a large batch will not exhaust your browser memory. A file that turns out to be corrupt fails on its own and the rest of the batch carries on.
