All processing happens locally in your browser. Files are never uploaded to any server.
Large PDFs are a headache — email services reject them, mobile sharing is slow, and cloud storage fills up fast. iLoveConvert's free PDF compressor re-encodes images inside your PDF at optimized quality levels, dramatically reducing file size without visible degradation. No watermarks. No upload. No waiting for a server.
Most online PDF compressors send your sensitive documents to cloud servers, where privacy is uncertain. Our tool compresses entirely in your browser using PDF-lib, so financial statements, legal contracts, and personal documents stay completely private.
Drop your PDF into the upload area or click to browse.
Select Low, Medium, or High compression. Higher = smaller file, lower quality.
Click Compress PDF. The tool re-encodes images within the PDF.
Download the compressed PDF. Check before/after file sizes.
Typical results: 30–70% smaller. PDFs heavy with high-res photos compress most. Text-only PDFs compress less since text is already efficient.
No. Text in PDFs is vector-based and is not affected by image compression. Only embedded images are re-encoded.
No server-side limit — the limit is your device's RAM. Most files up to 200 MB process fine on modern devices.
Unlock the PDF first using our Unlock PDF tool, then compress it.
Never. iLoveConvert is 100% free with no watermarks, ever.
