Compress PDF to 1MB — why it works this way
1MB is a tight target, usually hit by re-rendering each page as a smaller, more compressed image and rebuilding the PDF from those — this works best for scanned documents or PDFs full of photos. Every attempt happens locally in your browser via a search over image quality, so nothing is uploaded to find the right setting.
Is my file uploaded? No. Everything happens locally in your browser using the Canvas/File APIs — your file is never sent anywhere.
FAQs
Is my PDF uploaded anywhere first?+
No — compression happens entirely in your browser.
Will this always reach exactly 1MB?+
It gets as close as possible while staying under 1MB and keeping the pages readable — some PDFs (very long, or with dense diagrams) may not compress all the way down without losing too much legibility, and the tool will tell you if it couldn't quite hit the target.
Will text still be selectable?+
No — pages are converted to images to shrink them, so text stops being selectable/searchable in the compressed output.
What if 1MB is too tight?+
Try the 2MB or 5MB targets, or use the main Compress PDF tool with a quality level instead of an exact target.
