How to compress a pdf to under 1mb using lossy compression
- Step 1Upload the PDF — Drop the document into the compressor.
- Step 2Set maximum compression — Choose the lowest quality setting (50-60%) for maximum size reduction.
- Step 3Check the output size — If still over 1MB, reduce the page count using PDF Split first.
- Step 4Download and submit — Save the compressed file and upload to the target system.
Frequently asked questions
Is 50% quality sufficient for a CV or resume?+
For text-dominant CVs, 50-60% quality produces a readable PDF under 1MB. Avoid very low quality on CVs with photos — image quality will be noticeably reduced.
What if the PDF is still over 1MB after maximum compression?+
Remove images or convert the document to text-only. Alternatively, reduce the page count using PDF Split.
Will the font rendering be affected by lossy compression?+
No — font rendering is vector-based and is not degraded by lossy image compression. Only embedded raster images are affected.
