How quality is preserved
The default quality is 85. Compression re-encodes the image, so preserve the original separately when exact source data matters.
Privacy and file security
Files stay in browser memory. Download URLs are revoked after use, and closing the tab removes the temporary data. File names and file contents are never sent to analytics.
Use on mobile and desktop · Large file guidance
The tool works in modern desktop and mobile browsers without installing software. Large jobs are more reliable on a device with more free memory.
Images are processed one at a time. Compare the generated size and zoomed preview because compressibility varies by image content.
Common errors and fixes
PNG size may not decrease much for some images. For photographs, JPG or lossy WebP usually produces a larger reduction.
Frequently asked questions
Do I need an account?
No. The tool works without sign-up, login, email or payment.
Are my files uploaded?
No. Supported work is performed in your browser and result files are downloaded directly to your device.
Will quality be reduced?
Not unless you choose compression, resizing or a lower DPI. Lossy output formats can still change image data.
Can I use it on a phone?
Yes. Modern mobile browsers are supported, but large PDFs may need more memory than a phone provides.
What happens when I close the tab?
Temporary browser memory and generated download URLs are cleared.
