Frequently Asked Questions
Will compressing the PDF make it blurry?
Our compression engine targets the embedded images within the PDF, which cause most file bloat. Vector graphics and text remain perfectly sharp. Images will be optimized for web transmission, meaning they compress significantly but remain completely legible.
Who uses the PDF compressor?
Administrative assistants shrink large reports to bypass email attachment limits (usually 25MB). Web developers compress marketing PDFs to improve website loading speeds. Paralegals shrink evidentiary documents to meet court e-filing file size caps.
How much smaller will my PDF get?
The compression ratio depends on the original file. Image-heavy PDFs or scanned documents can often be reduced by 40–70%. Text-heavy PDFs that are already optimized may only see a 10–20% reduction.
Are my confidential PDFs safe?
Yes. The data compression runs entirely inside your browser via WebAssembly. Your corporate financial sheets, NDAs, and proprietary blueprints are never uploaded to any external server.

Real feedback from people who use DoctorDocs every day.
"Construction drawings exported from AutoCAD routinely come out at 80–100 MB. Most client portals cap uploads at 25 MB. I run them through here and get files under 10 MB with no visible loss in drawing quality. It's part of my standard export process now."
"US university portals are notoriously strict about file size limits for transcripts and SOPs. I help students compress their documents before uploading so they don't get error messages at the last minute. Reliable every single time."
"My pension documents are scanned at very high resolution and end up as huge files. I needed to email them to my bank but the attachment was too large. This compressed a 45 MB PDF down to 4 MB without making the text unreadable. Simple enough for me to use without any help."
While our tool is highly secure and optimized, always keep a backup copy of your original files, and verify the readability of highly detailed diagrams or fine print after compression.
