Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions
About this tool
Is my file uploaded?
No. TIFF decoding, image encoding, and document assembly run on this device.
