Resize image FAQ

How do I resize an image?

Drop your files onto the upload area, type a new width (or set a percentage), and click Resize. With aspect ratio locked, the height adjusts automatically. You can then download each image or all of them as a ZIP.

Will resizing reduce the quality of my image?

Downscaling re-samples the pixels using a high-quality interpolation, which keeps the result sharp. Upscaling beyond the original resolution will always soften the image — there are no extra pixels of detail to add.

Can I resize multiple images at once?

Yes. The resizer is fully batch-capable: select or drop as many files as you like and they will all be resized in parallel using the same settings.

What formats can I resize?

JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC/HEIF photos from iPhone are all supported. Output can be the same format or converted to JPG, PNG, WebP, or AVIF.

Is anything uploaded to a server?

No. The resizer uses your browser's Canvas API — your images are processed locally and never leave your device.
