How SuperUltraMegatonFreeTool works

Free browser-based PDF and image tools with no account, no watermark and no file upload.

How to use this tool

1. Choose one or more supported files.
2. Review the file name, size and detected properties.
3. Choose only the settings you want to change.
4. Start processing and follow the progress.
5. Preview the result and download it directly.

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.

How quality is preserved

The original pixel size and page ratio are kept unless you choose a resize, compression or lower DPI setting. Lossless formats stay lossless where the browser encoder supports it.

Large file guidance

PDF pages are processed one at a time. The tool never reduces quality automatically. If memory is insufficient, lower DPI or split the job yourself.
