Crop to an exact size — by dragging, or by typing the numbers

Every field on the form wants a specific rectangle. Drag the box if that suits you, or type the coordinates and get the same pixel every time. It will not enlarge your photo to fake a size.

Nothing is uploadedYour browser opens the file and does the work. There is no server to send it to, so there is nothing to leak, log or delete later.
No account, no sign-upNothing to sign up for, and no cap on file size. Free runs one file at a time, forever. Pro takes a whole batch in one pass.
No upload, no waitingWork starts the moment you drop the file. A 40 MB photo does not have to travel to a data centre and back.

You can type the numbers instead of dragging

Dragging a box with a mouse is fine until the form wants exactly 413 × 531 pixels starting 88 pixels from the left. The fields above take the rectangle directly, and the nudge buttons move it a pixel at a time. That is not only a convenience: WCAG 2.2 requires that anything you can do by dragging can also be done without dragging, and W3C is explicit that keyboard support alone does not satisfy it — the alternative has to be clickable too. So the buttons are the accessible path, and they happen to be the precise one as well.

The crop comes from the original pixels

The picture on screen is scaled down to fit your window. A surprising number of croppers then cut from that scaled-down copy, so a crop of a 4000 px photo quietly comes back at display resolution and looks soft. Here the rectangle is stored in original image coordinates the whole time and only projected onto the preview for display. What you get out is cut from the full-resolution original.

Locked ratios do not drift

Ask for 16:9 on an 800 × 450 image in a lot of tools and you get 800 × 449 — the height is recomputed from an already-rounded width, and the error compounds. This one derives the locked edge from the long side and rounds exactly once, so 16:9 on that image stays 800 × 450.

It will not enlarge your photo

If you ask for an output larger than the area you cropped, the tool says so and stops rather than stretching. Enlarging invents pixels that were never photographed; the file will hit the size the form asked for and still look wrong to whoever reviews it. Better to know now.

A caution about official photos

Specification presets here come from the issuing authority where one publishes exact pixels — the US visa digital photo is 600 × 600 to 1200 × 1200 px, square, 240 KB or less, and the UK digital passport photo is at least 600 × 750 px and at least 50 KB. Note that the US State Department asks for an unedited photo and tells applicants not to use digital tools to alter it. Cropping to a required size is not retouching, but read your own portal's wording before you rely on any tool, including this one.

How to crop an image to an exact size

  1. Drop in the photo you want to cut down.
  2. Drag the box, or type the exact width, height and offset in pixels.
  3. Rotate or flip if you need to, then press Crop and download.

MOV to MP4Turn an iPhone .mov into an .mp4 by swapping the wrapper, with the video copied across and nothing re-encoded. Trim a videoKeep the part you want. The clip is copied rather than re-encoded, so no quality is lost. Split into partsCut a long recording into pieces short enough to post, without re-encoding any of them. Rotate a videoChange the rotation flag a phone wrote instead of re-encoding the picture. Seconds, not minutes. Remove the soundDrop the audio track and copy every frame across untouched — same quality, same size. Video to MP3Convert a video’s sound to MP3, or lift the original audio out byte for byte with nothing re-encoded. Video to GIFPick a range, a frame rate and a size, and get an animated GIF back with nothing uploaded. Green screen swapSwap a green or blue screen for a solid colour with a live preview, no AI model and no watermark. Silence removerFinds the quiet stretches by listening to the audio and cuts them out, with a timeline showing every cut first. Blur pad to a new ratioFit a video into 9:16, 1:1 or another shape with a blurred background instead of black bars. Compress a videoAim at a Discord, email or WhatsApp limit — or your own — and get an MP4 checked afterwards, not just promised. Noise removerLearns your recording’s own background hiss or hum from a quiet stretch, then subtracts exactly that. Auto-reframeCrops a landscape clip to a new shape and pans the crop to follow the motion, instead of a fixed centre. CaptionsBurns an .srt or .vtt subtitle file into the video as styled, timed on-screen text. Beat syncFinds the beats in the clip's own audio and lands a flash or a zoom-punch on each one. Highlight finderScores a clip by loudness and movement, and ranks the best stretches to cut out, losslessly.
