Everything is processed on your device — nothing is uploaded.
📐Exact pixel dimensions, no distortion
Portals and forms demand exact pixels — 200×230 for a photo, 140×60 for a signature. Type a width or height and the other adjusts automatically to keep proportions; untick the lock only when a form insists on exact-but-unproportional dimensions. The original size is shown up front, and the download is named with its new dimensions.
💡Common required sizes
- Passport-style photo uploads: often 200×230 px or 3.5×4.5 cm at ~200 px/inch.
- Signature uploads: commonly 140×60 px — crop tightly around the signature first.
- Profile pictures: most platforms want a square — crop to 1:1 first, then resize.
- Shrinking is safe; enlarging beyond the original always softens — start from the biggest source you have.
🔗Resize, crop, or compress?
- Wrong dimensions → resize (this tool). Wrong framing → Image Cropper. Too many KB → Image Compressor.
- Most portal photo rules need all three, in that order: crop → resize → compress.
💡 Frequently Asked Questions
Will resizing stretch my image?+
Not if you keep 'Lock aspect ratio' on — width and height stay proportional. Turn it off only if you deliberately want to stretch to exact dimensions.
Is there a maximum image size?+
It's limited only by your device's memory since everything runs locally. Very large images may take a moment to process.
