Why 450KB is a comfortable target
450KB is generous compared with 80KB or 100KB limits, so quality is rarely an issue. A single high-resolution scan or photo keeps most of its detail, and you can merge several pages into one PDF and still stay under 450KB. If your portal actually asks for “under 400KB,” just type 400 in the custom box — the same tool handles it.
Need a different size? The same engine powers the main JPG to PDF converter, where you can set any KB target from 80KB up.
How JPG to PDF at an exact KB works
A PDF made from photos is basically a wrapper around the images inside it, so its size tracks theirs. For a JPG to PDF at 450KB, the tool fine-tunes each image’s JPEG quality until the whole PDF sits just under 450KB — and because 450KB is roomy, it rarely has to sacrifice much detail. It’s all measured in your browser before you download.
Add your images
Drop one JPG or many. Reorder them so the pages come out in the right sequence.
Set the target
Pick a page size and a KB limit — below 100KB, 80KB, 150KB or your own number.
Convert & download
Hit convert. See the final size, then download your PDF. Done.
Why set the PDF size in KB?
Most "convert jpg to pdf" tools give you whatever file size they feel like. That fails the moment a portal caps uploads at a fixed number. Setting the size in KB is what turns a generic converter into something you can actually submit.
- Job & government forms: many require a document PDF under 100KB, 150KB, or 300KB.
- Visa & university portals: common ceilings are 300KB, 400KB, 450KB and 500KB.
- Very strict uploads: some ask for a JPG to PDF at 80KB or even below — this tool can hit those too.
- Email & chat limits: a smaller PDF sends faster and won't bounce on attachment caps.

Tips for a small, readable PDF
Keep text legible at 80KB
For a scanned document, crop out empty margins before converting — the tool then spends the KB budget on the text, not blank space, so a JPG to PDF at 80KB stays readable.
A4 vs "fit to image"
Choose A4 or Letter when a form expects a standard page. Use Fit to image for photos, ID cards, or receipts where you don't want white borders.
Very small targets
A busy, colourful photo can't always reach a tiny limit without going blurry. If the PDF stays above target, the tool tells you and gives you the smallest version it could make.
Compress the image first
Starting from a huge phone photo? Run it through the image compressor first for the cleanest result at strict limits.
FAQ
Common questions
How do I convert JPG to PDF 450KB?
This page opens with the 450 KB target selected. Add your JPG and press Convert to PDF — the tool keeps quality as high as possible while landing the finished PDF under 450KB, and shows the exact size before download.
Can I choose a custom KB size?
Yes. The 450KB target is only a starting point. Use another preset, or type any number in the custom KB box — for example 400 for an “under 400KB” requirement — and the converter aims just under it.
Does this work on mobile?
Yes. The converter runs entirely in your mobile browser on Android and iOS, so you can build a 450KB PDF from photos on your phone with no app to install.
Can I combine multiple images under 450KB?
Absolutely. Add several images, drag to reorder them, and each becomes a page. With a 450KB budget you can usually fit several good-quality pages in one PDF.
Will the quality drop at 450KB?
Much less than at tighter limits. 450KB is roomy, so most scans and photos keep their detail. Quality only drops if you pack many high-resolution images into a single file.
Are my files uploaded anywhere?
No. The entire conversion happens locally in your browser. Your images and the PDF never leave your device.
