FAQ
Common questions
We've got answers.
You can resize any format that supports both decoding and encoding, including JPEG, PNG, WebP, BMP, GIF, TIFF, QOI, TGA, EXR, HDR, ICO, PNM, and Farbfeld. The output is saved in the same format as the input.
No. The resizer preserves the original file format. A JPEG stays a JPEG, a PNG stays a PNG. If you need a different format, use the converter first.
Scaling down generally looks fine. Scaling up will soften the image since there is no lossless way to add detail that was not there originally. The resizer uses Lanczos3 filtering for the best possible result.
When the lock is active, changing the width automatically updates the height to maintain the original proportions, and vice versa. Unlock it to set width and height independently.
No. All processing happens in your browser using WebAssembly. Your images never leave your device.
