Compress PDFs to fit a 500KB upload limit — generous enough for image-rich documents with multiple pages and signatures. Browser-based, no upload.
500KB is the upper end of common upload limits — generous enough that most well-prepared documents fit easily without aggressive image down-sampling. Useful for portals that want detailed visual content (project samples, certificates, ID proof, photographs) in a single PDF.
Choose your PDF and click. The tool applies pdf-lib's object-stream compression. PDFs under 500KB pass through with minor optimisation; larger PDFs benefit more from compression.
Use it for university applications with portfolios, scholarship programmes that ask for detailed evidence documents, e-tender submissions with multi-page proposals, and corporate onboarding forms with several attached documents.
500KB allows 5–6 photos plus several pages of text — generous. For maximum quality at this size: keep images at 80% JPG quality, scan documents at 200 DPI grayscale, embed only essential fonts. Most well-prepared documents fit comfortably.
It balances quality and file size — generous enough not to need aggressive optimisation, small enough to email or upload comfortably.
