Fix "Upload Failed — File Size Exceeds Limit" PDF Error
Online portals, government websites, and HR systems often cap PDF uploads at 2-10 MB. Here's how to compress your PDF below any portal's limit without losing required content.
"Upload failed — file size exceeds the maximum allowed" is especially common on government portals, job application systems, university admissions portals, and HR platforms that haven't updated their file size limits in years. Limits of 2 MB, 5 MB, or 10 MB are typical. Modern PDFs — especially scanned documents or those exported from design software — routinely exceed these.
Know the Exact Limit Before Compressing
Portal error messages usually state the exact limit: "Maximum file size: 5 MB" or "Files must be under 2 MB." If the message is vague, check the portal's FAQ or help page. Knowing the target size lets you choose the right compression level and verify success before re-uploading. For a 2 MB limit, you need aggressive compression. For a 10 MB limit, a single Low compression pass is usually sufficient.
Single-Pass Compression (Most Cases)
Visit FixMyPDF's compressor in any browser. Upload your PDF. For limits of 5 MB and above, try Medium compression first — it achieves 40-60% file size reduction on most documents. For limits of 2-3 MB (common on government portals), use High compression. Download the result and check the file size before uploading. If the compressed file is still above the limit, try the advanced approach below.
If the PDF Is Still Too Large After Compression
Some PDFs contain extremely high-resolution images (300 DPI from professional scanners) that survive even aggressive JPEG compression at large file sizes. For a scanned document: try running through the compressor twice — first on High, then on High again. This occasionally achieves additional reduction the first pass misses. Alternatively, if you're scanning documents specifically for this upload, scan at 150 DPI instead of 300 DPI. 150 DPI is sufficient for text documents and reduces file size by approximately 75% compared to 300 DPI.
Submitting Multi-Document Applications
Many portals that accept PDF uploads (visa applications, job applications, university admissions) accept one PDF combining multiple documents — and the 2-5 MB limit applies per file. If you need to submit a CV, cover letter, and certificates as one PDF, merge them first with FixMyPDF's merge tool, then compress the merged file. The combined approach — merge then compress — typically results in a smaller file than compressing and merging separately, because the compressor can optimise shared resources across the whole document.
When the Limit Is Genuinely Too Restrictive
Some older portals have a 1 MB limit — virtually impossible to meet with multi-page scanned documents without unacceptable quality loss. Options: (1) Contact the portal's support to ask if they accept documents by email as an alternative. (2) Check if they accept JPG images instead of PDFs — a single JPG can be much smaller than a PDF with the same content. (3) Submit the minimum number of pages — if submitting proof of address, scan just the one relevant page rather than the whole 20-page bank statement. Cropping out white margins also reduces size: use FixMyPDF's crop tool before compressing.
