Image Resizer FAQ
Can I upscale images?
Yes, but upscaling cannot add detail beyond the original—results may look soft if you enlarge far beyond the source size.
Does resizing reduce quality?
Downscaling keeps sharp detail; JPEG and WebP use your quality slider, while PNG export is lossless.
Which formats are supported?
Input: JPG, PNG, WebP, BMP, and GIF. Output: JPG, PNG, or WebP.
What does lock aspect ratio do?
When enabled, changing width automatically updates height (and vice versa) so your photo is not stretched or squashed.
Is there a file size limit?
Each image can be up to 25 MB for smooth in-browser processing.
Do you upload my photos?
No. Resizing runs entirely in your browser—your images never leave your device.
