Compress a PDF to Under 5 MB — Free, No Watermark
Need a PDF under 5 MB to clear contact forms and many upload portals? This tool targets 5 MB for you automatically — open it from this page and the target size is already set. It uploads your file and searches for the highest image quality that still fits under 5 MB, using a professional Ghostscript engine that keeps your text selectable and searchable the whole time. No watermarks, no daily caps, no signup.
Can you get a PDF under 5 MB?
Clearing a 5 MB cap is comfortably within reach for almost any document. You don't pick a compression level — the tool automatically finds the setting that lands under 5 MB at the best possible quality, and shows you the exact final size along with a "target met" confirmation. Only very large, image-heavy scans are a challenge; if one can't reach 5 MB without becoming unreadable, the tool returns the smallest version it can and tells you honestly.

Frequently asked
Common questions about compressing a PDF under 5 MB.
Yes. This page opens the compressor with the target preset to 5 MB, so you just click Compress — the tool automatically searches for the highest image quality that still fits under 5 MB and applies it. You never pick a compression level yourself. It then shows the exact final size and confirms whether 5 MB was met.
Almost always because it's a large, image-heavy scan. Photos and scanned pages are stored at high resolution, and a stack of them can't always be squeezed to 5 MB without becoming unreadable. The tool already pushes to its smallest setting automatically; when even that can't reach 5 MB, it returns the smallest possible version and tells you honestly. Split the PDF into smaller files with our Split PDF tool and compress each part — a few small files under 5 MB is usually more useful than one that won't fit anyway.
Yes. Unlike compressors that flatten each page into an image, we use Ghostscript, which keeps your text as real, selectable, searchable text and only downsamples the images. Your compressed PDF stays a proper document however small the target.
You're aiming to stay under 5 MB, which covers contact forms and many upload portals. Gmail allows attachments up to 25 MB and Outlook up to 20 MB; many contact forms and government portals are stricter, at 5–10 MB. Targeting 5 MB clears these limits automatically for almost any document.
Yes — completely free, with no watermark, no daily cap, and no signup. Your file is uploaded over HTTPS, compressed, streamed back, and deleted from our servers immediately. Compress as many files as you like.
