Image resizer help
The image resizer exports a selected image at the original aspect ratio, updates the preview live, and can compress JPEG or WebP output from your browser.
Supported File Types
Use common browser-readable images such as PNG, JPG, JPEG, WebP, and BMP. Animated images, very large files, unusual color profiles, or files your browser cannot decode may fail or export only a still frame.
Local Processing And Privacy
PixTools does not require an account and does not upload your selected image to a PixTools server for resizing or compression. The preview and download are created locally by your browser.
Presets And Custom Sizes
Resolution presets are generated after upload from the original image size. They keep the same aspect ratio and scale down from 90% to 10% of the original resolution in 10% steps.
Custom sizing keeps width and height linked. Change either dimension and the other updates automatically so the full image stays visible without cropping or stretching.
Output Format, Quality, And Compression
Choose Same as original, JPEG, PNG, or WebP. The quality slider affects JPEG and WebP exports only; PNG exports ignore quality because browser PNG export does not use that setting. Lower quality values can reduce file size when your browser exports JPEG or WebP.
Downloads
The download button uses the visible preview settings. Filenames include the output dimensions and use the extension for the selected export format.
Related Tools
Use Image Compressor when the image dimensions are already correct and only the file size needs to change, or Image Converter when the file type is the main problem.
Troubleshooting
If the preview or download fails, try a smaller image, choose PNG or JPEG, refresh the page, or use a current version of Chrome, Edge, Firefox, or Safari.
Limitations
The current resizer does not crop, stretch, batch process, target a file size, edit metadata, or preserve animation. Review the output dimensions and file size before publishing.
FAQ
Will the tool crop my image?
No. The tool keeps the original aspect ratio and resizes the full image. Use a separate crop tool when you need to change framing or output shape.
Why is quality disabled?
Quality is only supported for JPEG and WebP exports. PNG exports keep the slider visible but disabled.
Can I get help with a bug?
Yes. Send the browser, image type, settings, and what happened through the contact page. Do not email private images unless you are comfortable sharing them.
