Secure your PDF with strong password protection and encryption.
Reduce file size without losing quality.
Government portals have strict document requirements: PDF/A format, 300 DPI resolution, searchable text, Section 508 accessibility, and file size limits. Our AI‑powered tool brings your PDFs into full compliance – upscale low‑resolution scans, apply OCR (searchable text), convert to PDF/A, redact sensitive data, and compress to meet size caps. Trusted by contractors, grant applicants, and agencies. Secure, compliant, and ready for submission.
Did you know? Over 30% of government submissions are rejected due to low resolution or missing searchable text. Our tool eliminates these rejections.
Scans at 150 DPI fail agency standards. Upscale to 300 DPI with AI.
Agencies require text‑searchable PDFs. Our OCR layer solves this.
Archival format mandated by many agencies. Convert to PDF/A‑1b.
Most portals accept only 25‑50 MB. Compress without losing quality.
Bonus – missing accessibility tags: Section 508 requires tagged PDFs. We can add basic reading order and heading tags.
Upload your PDF – Our system checks DPI, searchability, format, and file size.
Select "Government Submission" preset – Enables upscaling to 300 DPI, PDF/A conversion, and OCR readiness.
Apply AI enhancement – Despeckle, deskew, contrast, and upscale. The tool also flattens transparency and removes metadata if required.
Run OCR (optional) – Add searchable text layer. Then convert to PDF/A.
Download the compliant PDF – Ready for submission to SAM.gov, Grants.gov, or agency portal.
Pro Tip: Always check the agency's specific requirements (DPI, format, file size). Use our custom settings to match them exactly.
PDF/A (ISO 19005) ensures your document remains readable decades from now. It prohibits:
Most government systems require text‑searchable PDFs. Our enhancement pipeline prepares your scan for OCR:
Real‑world example: A federal grant applicant had 150 DPI scans of supporting documents. After enhancement and OCR, the PDF passed agency validation and was accepted on the first submission.
Section 508 requires electronic documents to be accessible to people with disabilities. Key elements:
Tip: After enhancement, use your agency's accessibility checker (e.g., PAC 3) to verify compliance.
⚡ Need to adjust or standardise DPI without changing pixels?
Use our dedicated PDF DPI Changer to view, adjust, or unify the DPI metadata of embedded images. Perfect for pre‑press compliance, print workflow validation, and preparing files for commercial printing without altering visual quality.
Most agencies require PDF/A format for archival (ISO 19005), 300 DPI minimum resolution, searchable text (OCR), and Section 508 accessibility (tagged PDFs). Our tool can convert your PDF to meet these standards.
Common rejections: file size too large (over 25-50 MB), low resolution (under 200 DPI), missing searchable text (image‑only scans), embedded JavaScript or forms, and lack of PDF/A compliance. Our enhancement fixes all these issues.
Absolutely. Our OCR‑prep enhancement cleans the scan (deskew, despeckle, contrast), then you can run OCR to add a searchable text layer. The result is a perfectly compliant searchable PDF.
PDF/A is an ISO‑standardised version of PDF for long‑term archiving. It forbids features like JavaScript, external references, and encryption that might break future readability. Many federal agencies mandate PDF/A. Our tool can convert any PDF to PDF/A-1b or PDF/A-3.
Our enhancement improves image quality, but for full 508 compliance, you need tagged PDFs with proper heading structure and alt text. We can add basic tags and reading order, but advanced accessibility may require dedicated software. We offer a "Accessibility Prep" mode that adds logical reading order.
Yes. Use our redaction tool before enhancement. Redact personal data (SSN, addresses) permanently. Note that redacted content cannot be recovered, so keep a master copy.
Yes, we use TLS 1.3 encryption, and files are auto‑deleted within 24 hours. For classified or highly sensitive documents, we recommend our offline desktop version (no upload). We are FedRAMP ready and can sign a Data Processing Agreement.
Many agency portals limit uploads to 25 MB. Use our compression tool after enhancement: downsample images to 200 DPI (if acceptable), remove metadata, and use JPEG2000 compression. We also offer a "Gov‑optimised" preset that balances quality and size.

Enhancing a PDF improves visual clarity by adjusting resolution, sharpening text edges, and increasing contrast between foreground and background elements. This process is particularly useful for scanned documents, blurry text, or faded paperwork.
Several factors may reduce the readability of a PDF document. Low-resolution scanning, aggressive compression, improper export settings, and camera-captured documents can all introduce blur or reduce contrast.
Modern PDF enhancement tools apply multiple processing techniques to improve readability.
PDF enhancement algorithms work by analyzing pixel density and grayscale distribution. Contrast adjustment increases the difference between text and background while sharpening filters reconstruct blurred edges. When combined with OCR preparation, enhancement dramatically improves machine readability.
