PDF Compression Targets
Choose a specific file size target and compress your PDF to fit. Common targets include email attachment limits, portal upload restrictions, and file sharing requirements. All compression runs locally in your browser.
When You Need PDF Compression
Email Attachment Limits
Most email providers cap attachments at 10–25 MB. A scanned multi-page document can easily exceed this. Compressing to 2–5 MB ensures your PDF sends without bouncing, while keeping text readable.
Job Portal Uploads
Workday, Taleo, and many HR portals cap resume uploads at 2–5 MB. If your resume includes a portfolio or embedded images, compression to under 2 MB is often necessary to submit successfully.
Government & Legal Filings
Court e-filing systems (PACER, state courts) often limit PDFs to 5–10 MB per document. Tax portals and visa applications may require under 500 KB. Precise file size control is critical for these submissions.
Cloud Storage Optimization
Compressing archived PDFs from 10 MB to 1 MB each can free up 90% of storage. For businesses storing thousands of invoices, contracts, and reports, this translates to significant cost savings on cloud storage.
Common PDF Size Limits by Platform
Know the exact size limits before compressing, so you hit the right target on the first try.
| Platform / Service | Max PDF Size | Suggested Target |
|---|---|---|
| Gmail | 25 MB | Under 5 MB |
| Outlook | 20 MB | Under 5 MB |
| Workday / Taleo (HR) | 2–5 MB | Under 2 MB |
| PACER (US Courts) | 10 MB per doc | Under 5 MB |
| IRS e-File | 15 MB | Under 5 MB |
| University Admissions | 2–10 MB | Under 2 MB |
| 100 MB | Under 5 MB | |
| Slack (free) | 1 GB total storage | Under 1 MB |
Frequently Asked Questions
- How do I compress a PDF to under 200 KB?
- Upload your PDF and select the 200 KB target. The tool reduces image quality within the PDF, removes metadata, and optimizes fonts to hit the target. For text-heavy PDFs this is straightforward; for image-heavy PDFs, visible quality loss may occur at very small targets.
- Does compressing a PDF make the text blurry?
- No. PDF compression primarily targets embedded images and metadata. Text rendered as fonts remains crisp at any compression level. Only scanned documents (where text is stored as images) may show quality loss at aggressive compression targets.
- What is the maximum PDF size for email?
- Gmail allows 25 MB, Outlook allows 20 MB, and Yahoo allows 25 MB per attachment. However, for reliable delivery (especially to corporate recipients with stricter limits), keeping PDFs under 5 MB is recommended.
- Is PDF compression reversible?
- No. Lossy compression permanently removes data. Always keep a copy of the original uncompressed PDF before compressing. If you need the full-quality version later, you'll need to work from the original file.
