About JPG to PDF under 100KB
Portals often ask for certificates or ID documents as a single PDF below 100KB. This tool does both steps at once: it places each image on its own page, then searches for the highest image quality that keeps the whole PDF strictly under 100KB. Photos are only shrunk as much as needed, so text in scanned documents stays readable.
How to jPG to PDF under 100KB
- Select your images (JPG, PNG or WebP) and put them in page order.
- Choose a page size.
- Click “Convert under 100KB” and download the PDF.
Frequently asked questions
Is it safe to convert my documents here? Are my files uploaded?
Nothing is uploaded. PDFToolsFast runs entirely in your browser using JavaScript and Web Workers, so your files stay on your device. You can even disconnect from the internet after the page loads and the tool keeps working.
How can several photos fit in one PDF under 100KB?
The tool lowers image quality, and if needed resolution, evenly across all pages until the PDF fits. Fewer or smaller images leave more room for quality.
Will my scanned certificates stay readable?
Resolution is reduced only after quality alone can’t reach the limit, and the highest quality that fits is kept. If text is too soft, convert fewer pages per PDF or use a larger limit.
Which page size should I choose?
A4 suits most official uploads. “Fit to image” makes each page the size of the photo and usually gives the smallest file.
Can I reorder the images?
Yes. Use the arrow buttons next to each file before converting; each image becomes one page in that order.
