Your images never leave your browser

Drop or select the image you want to resize.

Enter width/height or a percentage. Keep aspect ratio on if you want proportional scaling.

Preview the result and download your resized file.

Can I keep the aspect ratio?

Yes. Leave “Maintain aspect ratio” checked and edit width, height, or percentage — the other values update automatically.

What is the maximum size?

Input files up to about 25 MB are supported. Output dimensions are capped at 10,000 px per side to protect browser memory.

Does resizing upload my photo?

No. Resizing uses the Canvas API in your browser. Your image never leaves your device.

Can I enlarge a small image?

Yes, but enlarging beyond the original resolution can look soft or pixelated. Shrinking usually looks cleaner.

Which format should I download?

JPEG is great for photos, PNG for graphics with sharp edges or transparency needs, and WebP for modern web pages.
