Many job portals, college admission forms and visa document checklists cap each file at 500 KB. That is enough room for a CV, an offer letter or a few scanned pages to stay crisp, so the aim here is a smaller file that doesn't look compressed. This page opens Compress PDF with a 500 KB target ready.
Your CV, salary slips and passport scans are compressed by your own browser and never uploaded, which makes this a sensible place to prepare the documents for an application.
How to compress a PDF to 500 KB
- Choose the PDF, or several, or drop them onto the page.
- Leave Compression on Target size, with 500 in Largest file size (KB).
- For a CV or any document that software will read, untick "If needed, turn pages into images to reach the size", so the text always stays text.
- Select "Compress", check the before and after sizes in the note, and download.
What to expect at 500 KB
Most everyday documents fit with little or no visible change. The tool keeps the gentlest setting that fits, so images are re-saved at high quality and resolution whenever the size allows. A typed document that is over 500 KB usually carries a large photo or logo, and re-saving that one picture is often all it takes.
Text, fonts and drawings are left as they are while the pictures are re-saved, so headings stay sharp at any zoom and words can still be selected and copied. Pages only become images as a last resort, and only while that option is ticked.
Keeping a CV readable by software
Many recruitment systems read the text inside your CV, and a page turned into an image has no text for them to read. With the option unticked, the tool only re-saves the pictures; if the file still won't fit, it tells you instead of flattening your CV. The fix is then usually a smaller photo, or saving the CV again from your word processor without high-resolution images.
Frequently asked questions
Does 500 KB mean 500,000 bytes?
Here, yes. A KB is 1000 bytes, so the result is under 500 KB whichever way a portal counts. If your file is already under 500 KB, it is kept as it was or only tidied without loss.
Will my scanned documents still be clear?
A few scanned pages usually stay clear at 500 KB. A long scan has to share the space between more pages, so look at the result before you submit it, and split it with Split PDF if the form takes several uploads.
Can I compress a Word file to 500 KB?
Save it as a PDF from Word first, then compress the PDF here. For photos rather than documents, use Compress image.
Is there a limit on how many files I can compress?
No. There is no daily limit and no sign-up, and nothing is uploaded, so very large files are limited only by your device's memory.
