Convert JPG to PDF
below 100KB
Turn one or many images into a single PDF that lands below 100KB — the ceiling most job forms, NADRA, and university portals set. This page opens with the Below 100 KB target already selected, so you just add images and convert. It also handles jpg to pdf under 100kb and less than 100KB requests.
Need the images smaller first? Use the image compressor to hit a KB limit, or the image converter to turn HEIC or PNG into JPG before you build the PDF.

What actually fits in a 100KB PDF?
100KB is a tight but workable budget. A single scanned form, an ID card, or a typed document page fits comfortably and stays sharp. One full-colour photo also fits, though fine detail softens a little. Merging four or five busy photos into one PDF under 100KB means each page gets ~20KB, so expect visible compression — crop out blank margins first and it stays readable.
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 built from photos is mostly just the images inside it, so its size is set almost entirely by them. To get a JPG to PDF below 100KB, the tool re-encodes each image at a lower JPEG quality — and scales it down if needed — until the whole PDF measures under 100KB. Everything is measured live in your browser, so you see the real size 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 make a JPG to PDF below 100KB?
Add your JPG (this page already has the Below 100 KB target selected), then press Convert to PDF. The tool compresses the image until the finished PDF is under 100KB and shows the exact size before you download.
Can I upload multiple JPG files?
Yes. Drop or select several images and each becomes its own page. Drag the rows to set the page order, then convert them into one PDF that still fits under 100KB where possible.
Why is my PDF still above 100KB?
Very detailed or high-resolution photos — especially several combined into one file — can’t always reach 100KB without going blurry. When that happens the tool gives you the smallest PDF it could make and tells you the size. Try fewer pages, crop empty space, or run each image through the image compressor first.
Is a 100KB PDF still readable?
For text documents and scans, yes — 100KB is plenty for legible pages. For photos, quality drops as the target tightens, but the tool keeps it as high as the 100KB budget allows.
Are my files uploaded to a server?
No. The whole JPG to PDF conversion runs locally in your browser. Your images and the finished PDF never leave your device.
Does it work on a phone?
Yes. It runs in Android and iOS browsers, so you can make a sub-100KB PDF straight from photos on your phone.
