About this tool
500 KB gives room for a multi-page scan or a report with pictures at screen resolution. The tool scales the pictures down in steps and stops at the first setting under the limit, so the result keeps as much quality as the limit allows.
The result lists each PDF with its old and new size and how many pictures were shrunk. Several PDFs can be done together and saved one by one or as a ZIP, so a set of supporting documents is ready for a portal in one go.
Frequently asked questions
Can I compress a PDF to 500 KB without losing quality?
On a screen, usually: the text is not touched, and pictures are kept at screen resolution whenever 500 KB allows. Print quality drops at the stronger settings, so keep the original for printing.
Can I set a different limit?
Yes. Change the number to anything between 20 and 50,000 KB, or open the 100 KB, 200 KB or 1 MB pages.
What if it cannot reach 500 KB?
The tool keeps the smallest version it made and says so. Splitting the PDF or allowing pages to become pictures gets further.
Is my PDF uploaded?
No. Everything happens in your browser.
PDF ka size 500KB tak kam kaise kare? (Can I get a PDF under 500 KB on my phone?)
Yes. The tool runs in the browser on iPhone and Android as well as on a computer, with the limit already set: add the PDF, tap "Compress to 500 KB", then save the file to Files or share it straight to email.
