Compress PDF Without Losing Quality
Large PDFs are a daily headache. Your bank won't accept a 12 MB scanned passbook, Gmail refuses an attachment over 25 MB, and that 80-page project report simply will not upload to the college portal. The quickest fix is not a new email account or a cloud link — it is to compress the PDF to a smaller size while keeping the text readable and the images sharp enough for print.
Our online PDF compressor does exactly that. You drop a file, pick a compression level, and download a smaller copy in seconds. Your first 2 compressions a day need no account (3 with a free one), there is no watermark, and the original file is removed from our server automatically within two hours. Whether you need to reduce a PDF to 100 KB for a government form, get a scanned document under 2 MB for a job portal, or shrink a dense eBook for WhatsApp sharing, the same tool handles all of it.
How Our PDF Compression Works
Most people assume compressing a PDF means cropping pages or deleting content. It does not. A PDF file is a container of text, fonts, images and metadata — and inside most documents, the images are the real weight. Our compressor re-encodes those images using smarter codecs, removes duplicate fonts, and strips hidden metadata that nobody reads. The visible content stays the same; only the overhead goes away.
1. Upload Your PDF
Drag and drop a PDF of up to 100 MB. It is uploaded over HTTPS, compressed on our server and deleted automatically within two hours.
2. Choose a Compression Level
Pick Extreme for the smallest file, Recommended for the best balance, or Low if you need to preserve print-grade images.
3. Let the Engine Work
Images are re-encoded, fonts are sub-set, and metadata is cleaned. Most files are done in a few seconds; large scans take a little longer.
4. Download and Share
Save the compressed PDF to your device, then attach it to an email or upload it wherever you need it. The original is auto-deleted within two hours.
Why This PDF Compressor Beats the Rest
Plenty of free compressors exist. Most leave visible JPEG artefacts, force you to register after the second file, or silently cap your daily usage. We built this one after getting tired of those limits ourselves.
Up to 90% Size Reduction
Scanned files with heavy images often drop from 40 MB to under 4 MB without any noticeable loss in readability.
No Signup to Start, No Watermark
Your first 2 compressions a day need no email or credit card. The output PDF is clean — no branding, no footer, no trial stamp.
Free Daily Allowance
Compress 2 PDFs a day free without an account, or 3 with a free account, with no forced waiting between files.
Works on Every Device
The compressor works in any modern browser on Windows, macOS, Chromebook, Android, and iPhone — nothing to install.
Preserves Text and Hyperlinks
Unlike tools that flatten pages into a single image, we keep the text selectable and all internal links intact after compression.
Privacy-First Processing
Files are uploaded over HTTPS and deleted from our server automatically within two hours.
