Files processed on compressimage.fun servers are automatically deleted within four hours. You can delete a completed job immediately.
Server tools
Compression, resizing, cropping, format conversion, metadata tools, watermarks, and favicon generation upload images to the same-origin processing API. Each temporary job uses a cryptographically random ID and a separate high-entropy access token. Files are stored under random internal names, not your filename.
The source, outputs, small private previews, and safe job metadata live in an isolated processor volume. A cleanup task runs at startup and periodically. Delete now removes the complete job directory immediately.
Browser tools
Image to Base64, Base64 to Image, Base64 Image Viewer, and Image to Data URI run in browser memory. Their file or pasted value is not sent to the processing API. The tools also set input limits to avoid freezing your tab.
Logs
Operational logs may contain a request ID, tool ID, format, coarse size bucket, duration, and a controlled error category. They do not intentionally contain image bytes, Base64 data, GPS values, access tokens, result URLs, or full original filenames.
Analytics
Analytics is off when no measurement ID is configured. If enabled later, the event layer sends only controlled categories such as tool ID, format, file-count bucket, and processing result. Filenames, image contents, EXIF, job IDs, access tokens, and free-form errors are excluded.
What metadata removal cannot do
Removing EXIF and GPS fields does not hide information visible in the pixels. Faces, signs, reflections, and document text may still reveal private details.
