Fastest way to get a PDF under 5MB
PDFs vary (text vs scans vs photos). This workflow gets most users to the “under 5MB” target quickly.
Most PDFs (recommended)
Start with Compact. It usually gets you under 5MB while keeping text sharp and layout professional.
If you MUST go under 5MB
If Compact isn’t enough (typically scans/photos), switch to Rasterize and lower Quality/DPI step-by-step until the output is under 5MB.
Scanned PDFs (image-heavy)
Scans are mostly images. Use Rasterize sooner and reduce DPI/quality gradually for reliable size reduction.
- Remove unnecessary pages (then compress again).
- Split into multiple PDFs under 5MB if allowed.
- For scans/photos, reduce DPI/quality further in Rasterize.
Why people compress PDFs to 5MB
“Compress PDF to 5MB” is usually a hard constraint for uploads and submissions. This page is optimized for that intent.
5MB upload limits (portals & e-filing)
Some portals and e-filing systems reject PDFs over 5MB. This page is built for the “under 5MB” constraint: compress → check size → strengthen settings if needed.
Faster email + sharing
Even if email supports larger attachments, a 5MB PDF sends faster and fails less on slow connections.
Mobile-friendly downloads
Smaller PDFs download faster and scroll smoother on phones—especially if they contain images.
Storage and performance
Reducing PDF size keeps archives lighter and improves load performance for files you open repeatedly.
How to compress a PDF to under 5MB (3 steps)
1) Upload your PDF
Upload the PDF you need under 5MB. The file is transferred over an encrypted TLS connection for processing.
2) Choose Compact or Rasterize
Start with Compact for best quality. If still above 5MB, switch to Rasterize and reduce quality/DPI step-by-step until it’s under 5MB.
3) Download & submit
Download the compressed PDF and upload it to your portal/form or attach it to email. No signup and no watermark.

Compress PDF to 5MB — FAQs
Can you compress a PDF to exactly 5MB?
Often you can get under 5MB, but “exactly 5MB” isn’t guaranteed because PDFs vary. Image-heavy scans/photos may require Rasterize with lower DPI/quality. Some PDFs are already optimized and won’t shrink much.
Is there a one-click “under 5MB” button?
Not reliably. Best workflow: Compact first → if still above 5MB, switch to Rasterize and lower DPI/quality step-by-step until it’s under 5MB.
What’s the difference between Compact and Rasterize?
Compact keeps the PDF structure (sharp text/vectors) while optimizing images and metadata. Rasterize converts pages to images at your chosen quality/DPI for maximum size reduction (best for strict limits).
Why is my PDF not going under 5MB?
Usually because it contains high-resolution images/scans, many pages, or is already compressed. Use Rasterize, reduce DPI/quality, remove unnecessary pages, or split the PDF if allowed.
Will Rasterize affect text selection or search?
Yes. Rasterize makes pages image-based, so text may no longer be selectable/searchable. If you need searchable text afterward, run OCR after compressing.
Is my PDF uploaded to your servers?
Your PDF is transferred over an encrypted TLS connection to our compression backend and Adobe PDF Services for processing. As with any online service, avoid uploading extremely sensitive documents.
Does it work on iPhone and Android?
Yes. Open this page in Safari (iOS) or Chrome (Android) to compress PDFs without installing an app.
What should I do after compressing for a portal?
If needed, split/reorder pages, then sign the PDF before uploading.
