Why do some portals require PDFs under 1MB?

Job portals, government services, and university application systems often cap uploads at 1MB to limit server storage and processing costs. This limit is especially common on older or government-run platforms that have not been updated for larger modern file sizes.

Can I always compress a PDF to under 1MB?

It depends on the content. A 50-page PDF with high-resolution photos may not compress below 1MB while still remaining readable. For heavily image-based PDFs, try splitting the document into parts, compressing each separately, or converting to lower-resolution JPGs.

Will the text still be readable after compression to 1MB?

Yes. Text in PDFs is vector-based and is not degraded by compression. Only embedded images are affected. For mostly text documents, compression to 1MB rarely produces any visible difference.

Does FixTools add a watermark when compressing to 1MB?

No. FixTools never adds watermarks or branding to your compressed PDF. The output file is clean and ready to submit to any portal.

Is it safe to compress sensitive CVs or application documents?

Yes. FixTools processes your PDF entirely inside your browser using JavaScript. The file is never uploaded to a server, so your personal data remains completely private.

What if the portal still rejects my compressed file?

Check that the portal measures size in MB (not MiB). Also try removing any large images embedded in the PDF before compressing, or re-save the PDF from Word/Google Docs at a lower resolution before uploading.

How much can FixTools compress a typical PDF?

For scanned or image-heavy PDFs, compression of 50–80% is common. For mostly text PDFs, compression gains are smaller — typically 10–30% — because the text data is already compact.
