How to compress a PDF to 200KB in 3 steps
Add your PDF
Open Compress PDF and drop in your file. PDFs up to 200 MB work, including scans.
Choose Extreme
Extreme is the best starting point for a 200KB target. The tool shows the original and compressed sizes, so you can check the result straight away.
Check the size and download
If the new size is under 200KB, download it. If not, see the fixes below.
What fits in 200KB
Text barely adds to a PDF's size. Scanned pages and photos are what make it heavy. As a rough guide:
Swipe to compare →
| Your PDF | Level to try | Under 200KB? |
|---|---|---|
| Typed letter or résumé | Moderate | Almost always |
| 2–3 scanned pages | Extreme | Usually |
| ID scan front and back | Extreme | Usually |
| A long scan or photo-heavy PDF | Extreme, then trim or split | Sometimes |
If your PDF is still over 200KB
- Try the next level up, up to Extreme.
- Remove blank or unneeded pages with Delete PDF pages, then compress again.
- If it is a scan, re-scan at 150 DPI in grayscale. It makes a much smaller file to begin with.
- Still too big? Split the PDF into two files and upload each one if the form allows it.
Scan settings that land under 200KB
The easiest way to hit 200KB is to create a smaller file from the start. If you are scanning a document for a 200KB limit:
- Resolution: 150–200 DPI is plenty for reading and printing. 600 DPI makes files several times bigger for no visible gain.
- Color: grayscale for text, color for IDs.
- Pages: front and back of an ID on a single page.
- Phone scans: use the Notes app on iPhone (Scan Documents) or Google Drive on Android, which crop and flatten pages automatically.
How to check a PDF's size in KB
- iPhone: in the Files app, touch and hold the PDF and tap Get Info.
- Android: in Files by Google, tap the three dots next to the file and choose File info.
- Mac: select the file in Finder and press Command-I.
- Windows: right-click the file and choose Properties, or switch File Explorer to Details view.
Compress PDF also shows the original and compressed sizes on screen, so you can check before you download.
Where you'll run into a 200KB limit
- Job applications that ask for a résumé, certificates or references as separate files.
- College and program applications with transcripts and letters.
- ID and proof-of-address uploads for accounts and verification.
- HR onboarding portals.
Frequently asked questions
How do I compress a PDF to 200KB for free?
Open Zappy Compress PDF, add your file, choose Extreme and click Compress PDF. The new size is shown before you download, so you can confirm it is under 200KB.
Can every PDF be compressed to 200KB?
Not always. Long scanned documents may not fit in 200KB even on Extreme. Remove pages you don't need or split the file into parts.
Will the text still be readable?
Yes. Compression shrinks images and scans, not text, so typed words stay sharp at every level.
How do I get a scanned ID under 200KB?
Scan both sides onto one page at 150 to 200 DPI, then compress on Extreme. It usually lands well under 200KB.
Why do so many forms use a 200KB limit?
Small files keep older systems fast and storage costs low, so 200KB became a common default for document uploads.
Does it work on iPhone and Android?
Yes. Open Compress PDF in Safari or Chrome and choose the file from Files or your Downloads.
