compress pdf to 100 kb for visa portals and job boards
Use this page to compress pdf to 100 kb when a visa portal, a government form, or an older job board rejects anything heavier. A short text PDF usually hits 100 KB without extreme. A long scan of photos may not, and the page says so.

Steps to compress pdf to 100 kb
- Add the PDF with Choose files, or drop it on a desktop. It stays in this tab while you compress pdf to 100 kb.
- Confirm the target reads 100 KB. Balanced is selected so ordinary text stays selectable on the first try.
- Run the compress. The ladder stops at the first result under 100 KB, with at most six encodes.
- Download the PDF. If nothing landed under 100 KB, the note says this is the smallest file the ladder could make.
How this target is applied
The search is a fixed ladder. It starts at balanced, then tries stronger JPEG settings, then an extreme raster at 110 DPI and again at 80 DPI. It stops at the first result under 100 KB.
Balanced and the stronger JPEG settings recompress pictures already in the PDF and leave real text in place. Extreme makes text unselectable, because each page is redrawn as a picture.
Why 100 KB is the cap
Visa portals, government forms, and older job boards still refuse a PDF above 100 KB. The form measures the file before a person opens it, so a clear page that is too heavy never reaches the reviewer. Treat 100 KB as a hard gate, not a suggestion.
That gate is why a one page letter is a better candidate than a photo of every page in a packet.
What to expect at 100 KB
A short text PDF, such as a letter of a few pages, usually reaches 100 KB on balanced or on the next stronger JPEG setting. You should not need the 110 DPI or 80 DPI raster for that file.
A long scan of photos is different, because every page is already an image. The ladder may spend all six encodes and still finish above 100 KB.

Your file never leaves your device
Your PDF is processed only in this browser and is never uploaded. The work runs in a Web Worker in this tab, using WebAssembly for the heavy parts, and the result comes back as a local blob. This site does not upload the file, store it, or log its name.
To verify: load the page, turn on airplane mode, and drop the file again. It still finishes. Or open DevTools, choose Network, and watch the run: there is no upload. The architecture is described on How it works.
Frequently asked questions
Will a short text PDF reach 100 KB?
A short text PDF usually reaches 100 KB on the balanced step, because ordinary text packs tightly and the first encode is often enough. You keep selectable text, which matters when a reviewer copies a sentence later. Extreme is the wrong trade for a plain letter that already fits.
What if the PDF is a long scan of photos?
A long scan of photos may miss 100 KB. Each page is already a picture, so balanced and the stronger JPEG settings can only shrink those images so far. Extreme rasterises at 110 DPI and then at 80 DPI. The page says so if the cap is still missed after six encodes.
Does the extreme step keep text selectable?
No. Extreme makes text unselectable, because every page becomes a picture at 110 DPI and the last step repeats that at 80 DPI. You cannot search or copy those words afterwards. Earlier ladder steps leave real text in place, so hope the hit arrives before the raster.
How many encodes does the search run?
At most six. The order is balanced, then stronger JPEG settings, then extreme at 110 DPI, then extreme at 80 DPI. It stops at the first result under 100 KB. A short text PDF often ends on the first or second encode, so the harsher steps never run.
What do I get if 100 KB is missed?
You get the smallest file the ladder made, and the note says the target was not reached. That is more useful than a silent failure. It happens most often with a long scan of photos aimed at a tight cap. Drop spare photo pages and run again if the portal will not take the result.
