Need a picture at a specific size? Drop it above, type the pixels (or slide a percentage), and download. The aspect ratio stays locked so nothing distorts, you can switch format on the way out, and — as with every tool here — the image never leaves your browser.
How to resize an image
- Add your image — JPG, PNG, or WebP; you’ll see a preview with its current dimensions.
- Pick a mode — Exact pixels for form requirements, Percentage for quick scaling.
- Type the size — with the aspect lock on, the second dimension calculates itself.
- Click Resize, check the new file size, and download.
The “exact dimensions required” problem
Upload forms are fussy: job portals want 200 × 230 passport-style photos, marketplaces demand minimum widths, forums cap avatars at 128 × 128, and email signatures look broken above a few hundred pixels. Guessing in a photo editor wastes time — here you type the number the form asks for and you’re done. If the site also enforces a file size limit, run the result through the image compressor afterwards, or resize a little smaller.
Shrinking vs enlarging — what to expect
Downscaling is safe: pixels are merged, edges stay clean, and file size drops roughly with the pixel count. Upscaling is physics-limited — the tool resamples smoothly, but detail that was never captured can’t be restored, so a 4× enlargement will look soft. For social-media crops at specific ratios (square posts, story format), the crop tool is usually the better first step; crop to the shape, then resize to the target pixels.
Limits and tips
- Formats: JPG, PNG, WebP in and out (files are checked by content, not name).
- Percentage mode goes up to 200% — beyond that, quality loss outweighs the size gain.
- Transparency: converting a transparent PNG to JPG fills the background — keep PNG or WebP when transparency matters.
- Size cap: 50 MB per image; processing time depends on your device, not a server queue.
Private by design
The whole pipeline — decode, resample, encode — runs in a Web Worker inside your browser. There is no upload endpoint, which is exactly what you want for photos of documents and IDs.
