WebP images supported
Dimensions are width × height in pixels. Suggested file sizes are compression targets, not platform limits.

Need another shape? Crop first, then resize and compress. Keep your original; do not sacrifice detail just to reach a suggested target. JPG is usually suitable for photos. Etsy does not preserve PNG transparency.
Etsy and Pinterest guidance was checked on this date. Instagram, Facebook and vertical-canvas entries are practical ResizeFox suggestions, not a complete list of accepted dimensions or verified maximum file sizes. Check the destination’s uploader for its current limit: posting apps, advertising tools and APIs may have different requirements.
Select the WebP file whose stored size needs to be reduced.
Enter the required maximum in KB and choose dimensions appropriate for how the image will be viewed.
Confirm the resulting size and check important details before downloading.
WebP is designed for efficient web delivery and supports both photographic images and transparency. Some older workflows may still ask for JPG or PNG.
Compression reduces stored data. Compare the result at its intended display size because very low quality can create visible artifacts.
Prepare efficient images for modern web pages and content cards.
Keep transparency while using a web-focused format.
Match the dimensions expected by a publishing system that accepts WebP.
Compare an appropriately sized WebP with an oversized source on the real page.
FAQ
No. ResizeFox processes the selected file locally in the browser.
Not every image can reach a very low limit without major visual or dimensional loss. Inspect the reported output size before uploading it elsewhere.
Many modern browsers and publishing systems do, but a strict form may request JPG or PNG. Follow the destination's accepted-format list.
