Frequently Asked Questions
Compression results vary depending on the PDF content. Documents with large embedded images can see 50–70% file size reduction. Text-heavy PDFs with few images may only shrink by 10–20% since text data is already compact.
Yes. PDF compression focuses on optimizing embedded images and removing unnecessary metadata. All text, fonts, and formatting remain intact and fully selectable in the compressed output.
Absolutely. This is one of the most common use cases. Most email providers limit attachments to 25 MB. Our compression can often bring oversized PDFs under that threshold without noticeable quality loss.
Our standard compression is optimized for digital sharing and on-screen viewing. For documents intended for high-quality printing, the original uncompressed file is recommended, as image optimization may slightly reduce print resolution.
No. Compression is a one-way process — the original data that was removed or optimized cannot be recovered from the compressed file. Always keep your original files if you might need the uncompressed version later.
About the PDF Compressor
PDFs with embedded images, scanned pages, and rich formatting can balloon to enormous file sizes — often exceeding the 25 MB attachment limit of most email providers. The Cliply's free PDF compressor shrinks oversized PDF files by optimizing embedded images and stripping unnecessary metadata, all while preserving the document's text, fonts, formatting, and overall structure.
Our compression engine is intelligent about what it optimizes. Embedded photographs and scanned images are recompressed at optimal quality levels, while text, vector graphics, and fonts are left untouched. This means your compressed PDF looks nearly identical to the original on screen, but at a fraction of the file size. Typical reductions range from 30% to 70% for image-heavy documents.
The Cliply compresses your PDFs entirely in your browser. Nothing is uploaded to a cloud server, nothing is stored, and nothing is shared. This makes it the ideal tool for compressing confidential business proposals, legal documents with scanned signatures, financial reports, and any PDF containing information you want to keep private.
