Most oversized PDFs are large because of the images inside them, not the text. Doclium re-encodes and downsamples those images and reports the real before and after size, so you can see exactly what you saved rather than trusting a claim.
It depends almost entirely on the images inside. Image-heavy scans often shrink dramatically; a text-only PDF is already small and may barely change.
Yes. Compression targets images, so text and its searchability are preserved.
Yes. Doclium reports the actual byte size before and after, not an estimate.
Doclium is a free web app for working with PDFs: merge, split, compress, rotate, protect and convert them in your browser, with no install and no signup to start. Where most PDF tools stop at the file, Doclium also reads it — ask a question and get an answer that cites the page it came from, so you can check it.
Chat with a PDF, summarise a long report, or translate one into another language. Clean documents up with OCR, redaction, watermarks, headers and footers, page numbers and A4 or Letter resizing. Every change can be undone, and every export is previewed before it downloads.
