The form limit is 2 MB — can I hit that?+
Usually yes. Use a stronger compression level and check the resulting size; most documents drop well under 2 MB.
Will compressing reduce the quality of my PDF?+
Text stays crisp because it is vector-based. Image-heavy pages are recompressed, and you control how aggressive that is with the compression level.
Is there a file size limit?+
The tool runs in your browser, so it comfortably handles typical documents. Very large scans may take a few extra seconds to process.
