Compress your PDF for email and upload limits — right in your browser.
Loading editor…
To reduce a PDF's file size, open it above, pick a quality preset or a target size — 1MB, 500KB, 200KB or 100KB — and download the smaller file. Compression re-renders pages as compressed images, so scans and photo-heavy PDFs shrink the most, while a text-only PDF is already small and will gain very little. Free for 3 documents a day, compressed in your browser with no upload.
Drop it into the box above — it opens instantly, nothing is uploaded.
Click “Compress” in the toolbar and choose Balanced, Strong, or a target size like “Under 1 MB”. The editor shows the size before and after.
Click Download to save the compressed file — ready for email attachments and upload forms.
Get scans under the 10–25 MB attachment caps of Gmail and Outlook.
Meet the hard size limits of court, government and HR systems.
Make big documents practical to send and download anywhere.
Store years of scanned paperwork in a fraction of the space.
Most PDF compressors make you upload your file to their servers. DoceasePDF compresses entirely in your browser: pages are re-rendered as optimized images at a quality level you choose, which dramatically shrinks scans and image-heavy documents.
Pick Balanced for crisp text at a good saving, Strong for the smallest size that still reads well, or a hard target — under 1 MB, 500 KB, 200 KB or 100 KB — and the editor steps down quality until your file fits.
One honest trade-off: because pages are re-encoded as images, text in the compressed file is no longer selectable. For scans that's irrelevant (they're already images); for text documents, compress a copy you're sending, and keep your original.
Continue your PDF workflow: Compress PDF to 1MB — Hit an exact size limit instead., Split PDF — Split first if one part is all you need. or Merge PDF — Combine files before compressing once.
DoceasePDF compresses by re-rendering each page as an optimized image at a quality level you pick. For scans and image-heavy documents — which are what actually blow past size limits — this routinely cuts 50–90% of the file size. For pure-text PDFs that are already tiny, rasterizing can grow the file instead; those documents rarely need compressing in the first place.
The honest trade-off: because pages become images, text in the compressed copy is no longer selectable. Keep your original for editing, and send the compressed copy where size matters.
Gmail caps attachments at 25MB, Outlook at 20MB, and many corporate mail servers at 10MB. A phone-scanned contract clears those limits after one pass of Balanced compression. For portals with hard caps — 5MB, 2MB, 1MB — use a size target instead and let the tool step down quality until the file fits.

Any modern browser on Windows, Mac, Linux, iPhone or Android. Nothing to download or install.
Edit, sign, organize and compress in a single session — no re-uploading between tools like on other sites.
Open the PDF in the tool above, click “Compress”, pick Balanced, Strong or a target size, then download. The size before and after is shown so you know exactly what you saved.
Scanned and image-heavy PDFs typically shrink by 50–90% depending on the level you pick. Pure-text PDFs are already small, and rasterizing them can even grow tiny files — compression pays off most on scans.
Balanced keeps text crisp at reading size. Strong and the small targets trade sharpness for size — the preview updates after compressing, so check it before downloading.
No. Compression runs in your browser — your file never leaves your device, unlike upload-based compressors.
Balanced compression gets most scans comfortably under Gmail's 25MB and Outlook's 20MB caps. Check the size shown after compressing, and step up to Strong if needed.
Tiny text-only PDFs can grow when pages are re-encoded as images — they were already smaller than an image of themselves. Compression pays off on scans and image-heavy files.
No — pages are re-encoded as images, so text becomes part of the picture. Keep your original file for editing and searching.
