About JPG to PDF (Under 400KB)

This page turns your images into one PDF under 400 KB. Pick your photos, press Convert To PDF, and download the file. The 400 KB target is preset, and the whole job runs in your browser. Nothing is uploaded.

The target is filled in already, so the flow is four short steps. Works the same on a phone and a computer:

Rotate, remove, or reorder any page before you press Convert. What you see in the grid is exactly what the PDF becomes.

400 KB sits just under the half-MB mark many uploaders enforce. It carries six to ten document pages with sharp text. Mixed batches work well too: a few photos plus several forms. Light pages keep their original quality untouched. Only the heavy photos are compressed, and only as much as needed. Need more or less room? Try JPG to PDF under 300KB or JPG to PDF under 500KB.

400 KB is not just a portal number. Files under half an MB send instantly on slow connections. They open fast on old phones and never bounce from email. A rent agreement, a set of receipts, or class notes fit comfortably. Each photo becomes one page, in the exact order you set. Light pages keep their original quality, so printed text stays crisp. Only large photos are compressed to make the total fit.

No server touches your files. The conversion happens on your own device, even on a phone. Nothing is uploaded or kept anywhere. Your documents stay yours.

Frequently asked questions

How do I make a PDF under 400 KB?
Add your images, and the tool compresses them just enough to bring the finished PDF under 400 KB while keeping the pages readable. The final size is shown before you download.
Can I control the page order?
Yes — drag the thumbnails into the order you want before creating the PDF. Each image becomes one page.
What page size does it use?
A4 by default, with a choice of Letter or a page that matches the image itself. Orientation and margins are adjustable too.
Can I combine different image formats in one PDF?
Yes. JPG, PNG, WebP and HEIC can all go into the same document.
Is my file uploaded to a server?
No. The whole tool runs as JavaScript inside your browser, so your file is processed on your own device and never leaves it. You can even load the page, disconnect, and it still works.
Is it free?
Yes — free and unlimited, with no sign-up, no watermark and no cap on how many files you run through it.
