How this works in your browser
The crop is performed by drawing only the selected region of your image onto a new HTML5 canvas sized to that region, then exporting the canvas. Because the source pixels are copied across one-for-one with no scaling, the kept area is pixel-identical to the original: cropping never softens or resamples what it keeps. The pixels outside the selection are simply never drawn, so they do not exist in the output at all. That is a genuine difference from PDF cropping, which sets a viewing rectangle and leaves the surrounding content sitting in the file.

| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |
Who uses Crop Image
Meeting an aspect ratio requirement
Crop to square or 16:9 for a profile picture, thumbnail or banner slot that expects a fixed shape.
Removing unwanted edges
Cut out a distracting background, a stray finger or the border around a screenshot.
Focusing on the subject
Tighten the frame so the important part of the photo fills it rather than sitting in the middle of empty space.

Frequently asked questions
Can I crop to a specific aspect ratio, like square or 16:9?
Yes, preset ratios are available alongside free-form cropping.
Does cropping reduce image quality?
No. Cropping simply removes pixels outside the selected area; the remaining pixels are untouched.
Can I preview the crop before saving?
Yes, the selection box shows exactly what will be kept before you confirm.
Is the cropped-away area really gone?
Yes, and this differs from cropping a PDF. Here the discarded pixels are genuinely absent from the saved image, so nothing outside the selection can be recovered. PDF cropping only narrows the visible window and leaves the hidden content in the file.
What is the difference between cropping and resizing?
Cropping keeps the original scale and throws away the parts you did not select. Resizing keeps the whole picture and changes its dimensions. If you need an exact size without distorting anything, crop to the right shape first and then resize.
Does cropping make the file smaller?
Usually yes, and often substantially, because file size scales with pixel count. Removing half the pixels typically removes a comparable share of the bytes.
Is my image uploaded anywhere?
No. The crop is applied on a canvas inside your browser tab.
