To resize an image free: pick a max size, then drop your images anywhere on this page. Each one is resized on your device with its shape kept and never upscaled, then saves back as a JPG. No upload, no file cap, no signup.
How sizing works
The number you pick is the maximum for the longest side. A 6000×4000 photo at "1920px" becomes 1920×1280: same shape, right size. Images already smaller than the target are left alone (upscaling only adds blur, so we don't).
FAQ
Can I resize a whole folder?
Yes. Drop them all, flip Auto-download, and each image saves itself as it finishes.
Does resizing reduce file size too?
Massively. Halving dimensions roughly quarters the file size. For an exact target like "under 200 KB," use compress to exact size instead.
