Good to know
Runs on your device
Your browser crops the image. Nothing is sent to a server.
Common ratios
Crop freely, or lock the box to square, passport (3.5:4.5), signature (3:1), 4:5, 3:4, 2:3, 9:16, 16:9 or 4:3, in portrait or landscape.
Rotate and mirror
Turn the image 90° left or right, or mirror it, before you crop.
Full resolution or exact size
The download is the selected area at its original pixel size, or scaled to an output width and height you type.
Frequently asked questions
Is my photo uploaded?
No. Cropping happens in your browser, and your photo never leaves your device.
Does cropping reduce quality?
Without an output size, the cropped area keeps the original resolution: a 1000 × 800 pixel selection gives a 1000 × 800 pixel file. Rotating and mirroring don't lose detail, because the crop is always cut from the full-resolution image. JPG and WebP are re-saved at 92% quality, which looks the same as the original and keeps the file small.
Which aspect ratio should I use?
3.5:4.5 matches passport-size photos and 3:1 suits signatures for forms. 1:1 suits profile pictures, 4:5 Instagram portrait posts, 9:16 stories and phone wallpapers, 16:9 video thumbnails and slides, and 2:3 portrait prints. Use the swap button for the landscape or portrait version.
Can I crop to an exact pixel size?
Yes. Type an output width and height and the selection is scaled to exactly that size. Pick the matching aspect ratio first so the picture isn't stretched, or type only one side and the other follows the selection's shape. For exam forms with KB limits, the Exam Photo & Signature Resizer does the crop, size and file size in one step.
Which formats can I crop?
Any image your browser can open, plus iPhone HEIC photos, which are converted to JPG on your device first. PNG, JPG and WebP are saved in the same format. GIF, BMP and other formats are saved as PNG.
