Compress PDF for job portals
Job portal upload fields typically limit files to 2MB or 5MB. Use the preset that matches the site's stated limit and check that your CV and cover letter remain clearly formatted and readable before submitting — particularly if they include charts or photos.

Security & privacy detailsHow this tool helps
Reduce the file size of your PDF documents instantly, right in your browser. Our PDF compressor uses smart optimization to shrink files by up to 90% while preserving text clarity, image quality, and formatting. Perfect for email attachments, uploading to portals, or saving storage space. Unlike other tools, your PDF never leaves your device - all compression happens locally using your browser's processing power. Choose from three quality levels: high compression for maximum size reduction, balanced for the best mix of quality and size, or low compression to keep near-original quality. Works with scanned documents, reports, presentations, and any PDF file. Use it when you need to split large PDFs for portal limits, compress PDFs on iPhone, reduce email attachment size.

Intent guide
Compress PDF for job portals is a common task with specific constraints: upload limits, mobile workflows, and privacy concerns. This guide is written for that intent and pairs directly with the tool above so you can act immediately.
When to use a 10MB PDF target
If your upload form, email system or job portal rejects large documents, targeting 10MB gives you a practical goal instead of guessing. Many PDF tools only offer vague quality levels, which forces you to re-run compression several times. PDFWhisk is designed around the outcome you actually need: a file that clears a known limit with acceptable readability.
A reliable workflow (without trashing readability)
Start by checking whether the PDF is image-heavy (scans, screenshots, photos) or mostly text. Image-heavy documents usually compress well; text-heavy PDFs may already be efficient and can show limited savings. Use the target preset first, then review the before/after size and quality hint. If the tool warns that your target would require heavy quality loss, step up to the next target or split the file into smaller parts.
Common UK use cases and what to watch for
People most often use this for CV uploads, tenancy documents, application forms, bank statements, and supporting evidence PDFs. For job applications, always open the output and zoom in on small text. For scanned statements and forms, check signatures, dates and reference numbers remain readable. If you're emailing the file, compress after you remove unnecessary pages to avoid over-compressing.
Why this page exists (intent-specific guidance, not generic fluff)
This page is focused on the real job: getting a PDF under 10MB (or close to it) with minimal friction, especially on mobile. Use the preset call-to-action above, then follow the related actions below if you need to split, delete pages or merge documents before final upload.
Job application workflow: merge only when the portal asks for one file
If a recruitment portal allows separate uploads, keep your CV and cover letter separate and compress each file only as much as needed. If it requires one file, merge first and compress afterwards so the optimiser can work across the combined document.
Before you upload/share
- Review the output before sending or uploading.
- Keep the original file until the recipient or portal accepts the document.
- Use the related tools below if you need to merge, split or compress as a follow-up step.
Frequently asked questions
Which UK job portals have file size limits?
Reed, Indeed, NHS Jobs, and Civil Service Jobs all impose limits — typically 2MB to 5MB per file. Check the specific field for the limit before compressing.
Should I compress my cover letter separately from my CV?
If the portal requires them as separate files, compress each individually and review both outputs before uploading.
Can I recheck the file size after compressing?
Yes. The download shows the output file size. If it's still above the limit, try a stricter preset or remove unnecessary pages.
