Change an image's dimensions and export a smaller file — free, no watermark, and
100% in your browser. Aspect ratio is preserved; nothing is uploaded.
How to resize an image
Drop your image above — JPG, PNG or WebP, processed locally.
Under Resize, pick a max width (1920 / 1280 / 800 / 640) or type a custom pixel width.
Choose a format and click Compress image to download the resized file.
Resize and compress in one step
SumoSquash scales your image down to the width you choose — the height follows automatically to keep the original
proportions — then re-encodes it to WebP, JPEG or PNG at your target size. It's ideal for shrinking phone
photos and screenshots for the web, email or forums. Everything runs locally with the Squoosh codecs, so your
images never leave your device and there's no watermark.
Does it keep the aspect ratio?
Yes — set a max width and the height scales automatically.
Can I resize and compress together?
Yes — choose a width and a format/target size; both happen at once.
Are my images uploaded?
No — resizing and encoding run entirely in your browser.
