Frequently Asked Questions

Yes, completely. There are no fees, no watermarks and no daily limits. Because all processing happens in your browser rather than on paid servers, the tool costs almost nothing to operate — and that saving is passed on to you.

No. There is no sign-up, no login and no email required. Open the page, add an image, and start resizing. Nothing about you or your files is registered anywhere.

Yes. The interface is mobile-first and works in current versions of Chrome, Safari, Firefox and Edge on Android and iOS, including the native photo picker and touch-friendly controls. Modern phones handle typical photos without difficulty.

Honestly: the name describes the search category, not the technology. The resizing is performed by your browser's native image engine using high-quality mathematical resampling — not a machine-learning model. The tool does not add AI-generated detail or upscale with super-resolution, and it does not claim to.

No. Decoding, resizing and encoding all run inside your browser tab using standard web APIs such as the File API and Canvas. You can verify this yourself: open your browser's network tools while resizing and you will see no image data being transmitted.

No. Because your images are never sent anywhere, there is no copy on any server to store, index or share. Everything exists only in your device's memory while the page is open and is discarded when you close the tab or load a different image.

Yes, once the page has loaded. Since nothing is sent to a server, an internet connection is only needed to fetch the page itself in the first place. After that, you can disconnect and keep resizing.

No. Canvas-based re-encoding produces a clean image without EXIF data, so camera settings, timestamps and GPS coordinates are removed. That is usually a privacy benefit when sharing photos publicly — but keep your original file if you need the metadata.

You can open JPG/JPEG, PNG, WebP, GIF, BMP and AVIF files, subject to what your browser can decode. Output can be saved as JPG, PNG or WebP — WebP export appears automatically whenever your browser supports encoding it, which every current major browser does. A GIF becomes a static image of its first frame.

Input files can be up to 20 MB and roughly 80 megapixels; output dimensions are capped at 10,000 pixels per side. These limits keep processing reliable across devices, since all the work happens in your device's memory rather than on a server.

Downscaling with high-quality resampling keeps images looking sharp at their new size, and PNG output is lossless. Enlarging always adds some softness, because new pixels must be estimated rather than recovered. For JPG and WebP, avoid pushing the quality slider below about 60%, where compression artifacts become visible.

Resizing changes the pixel dimensions of an image; compression changes how efficiently those pixels are stored, leaving dimensions untouched. The two meet in the quality slider, which controls compression on JPG and WebP exports. See the full guide on image resizing vs compression for a detailed comparison.
