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 JPG, PNG or WebP file you need to convert.
The output is fixed to another format; check how transparency and compression differ between the two formats.
Download the another format copy and open it once before sending it to another service.
JPG is widely supported and efficient for photographs. It does not preserve transparency, and repeated lossy saves can gradually reduce detail.
Conversion creates a another format copy. The source remains unchanged, but format-specific features such as transparency may not carry into the destination.
Prepare JPG, PNG or WebP files for content pages and responsive layouts.
Meet a service's documented requirement before submitting.
Create a practical viewing copy while keeping the original.
Standardize an asset for a larger composition.
FAQ
No. ResizeFox processes the selected file locally in the browser.
No. Renaming a file does not change its encoding. This tool decodes the source and creates a new file in the destination format.
Use JPG for many photographs, PNG when transparency or sharp graphic edges matter, and WebP for efficient delivery when the destination supports it.
