Crop Images Online — Exact Pixels or Aspect Ratio, No Upload

Crop a batch of images to an exact rectangle or a locked aspect ratio, then export as PNG, JPEG, WebP or AVIF.

Trimming a photo down to the part that matters is a per-image decision, which is why this keeps a separate rectangle for every file you queue. Frame each one by dragging over its preview, or draw a rectangle once and push it across the whole batch when the shots really were composed identically.

How to crop an image

  1. Drop your images or click the upload zone, then select a queued image once it has loaded.
  2. Choose Free or lock the frame to 1:1, 4:5, 16:9 or 9:16 in the aspect ratio menu.
  3. Drag a rectangle over the preview, or type Left, Top, Width and Height in pixels; press Apply this crop to every image if the whole batch shares one framing.
  4. Pick the output format and quality, press Process, and download a single file from its row or the full set with Download all as ZIP.

One rectangle per file, by default

Two photographs queued together are rarely framed the same way, and a single shared rectangle applied to all of them would quietly cut the subject out of every image except the one it was drawn on. Each queued file therefore remembers its own region, and files you never touched export at their original full size.

When a batch genuinely was shot on a tripod or produced by the same screenshot tool, an Apply this crop to every image button copies the current rectangle across, clamping it to fit each file's own dimensions.

Ratio locking for fixed-shape slots

Marketplaces, avatars and card layouts usually demand one shape rather than one size. The ratio selector offers Free alongside 1:1, 4:5, 16:9 and 9:16; with one active, the rectangle is constrained as you drag and is shrunk rather than nudged when it meets an edge, which keeps the proportion exact.

Underneath the preview, numeric fields show the region in the photograph's real pixel coordinates. Dragging updates them and typing updates the rectangle, so rough framing by eye and precise entry by hand are both available.

Aspect ratios for social media crops

Choosing what comes out the other side

The cropped region is drawn into a canvas at its exact size and encoded through the same WebAssembly builds of MozJPEG, OxiPNG, libwebp and libavif the rest of this site uses. Quality, lossless mode and PNG optimisation level are all exposed rather than fixed at some assumed default.

A single file downloads directly. More than one is collected into a ZIP, and each row in the queue also offers its own download link so you can take just the one you needed.

Cropping photos privately on a phone or desktop

The crop box is driven by pointer events, which browsers raise for a finger or stylus as well as a mouse, and it disables page scrolling while you drag so a touch gesture moves the frame instead of the page. Everything else, from decoding to encoding, happens inside the browser tab on whichever device you use.

No photo is sent to a server and no account is required. The free tier crops up to 40 images per run with unlimited runs, and a very large photo on a phone is limited only by how much memory the browser can give the tab.

Questions people ask about Image Cropper

What formats can I feed in?
Anything the browser itself can decode, which in practice means PNG, JPEG, WebP, AVIF, GIF and several less common formats. Output is limited to the four codecs listed above, so an exotic input format is read and then written as one of those.
Does cropping re-compress the parts I keep?
Yes, because the surviving region has to be written into a new file. Choosing a lossless output such as PNG or a lossless WebP avoids any additional generation loss, at the cost of a considerably larger result than a quality-tuned JPEG.
What happens if one image in the batch fails?
That row is marked failed with the reason shown beside it and the rest of the queue continues. A single corrupt or unsupported file never aborts a run, which is the entire reason for queueing many files rather than doing them individually.
How many images can I process at once?
The free tier covers batches of up to forty images, counted per run rather than per day's total. The queue itself has no fixed ceiling beyond that, and work is spread across several background threads so large batches stay responsive.
Can I crop a photo on my phone?
The page runs in a mobile browser and the crop frame responds to touch through pointer events, but we have not tested every phone. If a huge camera original fails to load, the browser likely ran short of memory for decoding it.
How do I crop a photo for Instagram or YouTube?
Lock the aspect ratio to 4:5 or 1:1 for an Instagram feed post, 9:16 for Stories and Reels, or 16:9 for a YouTube thumbnail, then drag the frame over the part you want to keep and export.
Are my photos uploaded when I crop them?
No. The preview comes from a local object URL, and the cropping and re-encoding run in background workers inside your browser tab, so the pictures stay on your device from the moment you drop them until you download the result.
