How to convert JPG to PDF

  1. Choose one or more JPG files, or drag them onto the drop area. Only .jpg and .jpeg files are accepted.
  2. Check the order of the list. Use the arrows to reorder pages and Remove to take out any image you do not want.
  3. Confirm the target size (currently 100 KB). It is editable, so change the number or the KB/MB unit if your limit differs, and pick a page size.
  4. Press Create PDF. Your images are embedded as they are when that already fits; otherwise they are recompressed gradually and the PDF is measured after each attempt.
  5. Read the result: the actual PDF size is shown with a clear Target met or Target not met message. Then download the PDF.

What a 100 KB PDF limit means

One hundred kilobytes is a common ceiling for document uploads. It is comfortable for a single scan or a cropped photo and tight for several pages. The tool keeps your JPEGs as they are when they already fit, and otherwise lowers JPEG quality and then dimensions in small steps, checking the real byte size of the assembled PDF each time. If the images cannot reach 100 KB without becoming unreadable, you will see the actual size and the reason instead of a false success.

The size you enter is a goal, not a promise. A PDF made from JPEG images is almost entirely the size of those images, so the result depends on how many images you add, their resolution and how detailed they are. This tool measures the finished file and reports the true byte count instead of assuming success.

Format and page settings

Accepted input: JPG images (.jpg and .jpeg are the same format). Each image becomes one page, in the order shown in the list. Choose A4 or US Letter to fit each image on a page with a small margin, with portrait or landscape chosen automatically, or choose “Match image shape” for pages that follow each image's proportions. Images are never stretched or cropped. PNG, WebP, HEIC and other formats are not accepted here.

When the untouched JPEGs already fit the target, they are embedded without recompression. Otherwise quality is lowered in steps (not below about 50 percent) and dimensions are reduced only as far as roughly 800 px on the long side. Photos stored with an EXIF rotation flag are re-encoded upright, since PDF viewers ignore that flag.

Practical uses

  • Single-page identity or address proof for an online application
  • A short two- or three-page set of small scans for an email limit
  • Signed forms photographed at modest resolution

Tips for a smaller PDF

  • Photograph documents in good light at moderate resolution instead of the maximum your camera allows.
  • Compress very large originals before combining them, then convert.
  • Check the result zoomed in: text should stay readable at the chosen size.

Frequently asked questions

How do I convert a JPG to a PDF under 100 KB?

Add your JPG files, keep or edit the 100 KB target, and press Create PDF. The tool builds the PDF in your browser and tells you the real size so you can see whether it is under 100 KB.

Will my images be recompressed to fit 100 KB?

Only when needed. If your untouched JPEGs already produce a PDF within 100 KB they are embedded unchanged; otherwise quality and size are reduced gradually and the notes tell you what happened.

Are my images uploaded anywhere?

No. Files are read and the PDF is generated entirely on your device. Nothing is sent to Paul Digital or any other server.

Can it guarantee the PDF will be under the limit?

No. The size depends on your images. The tool embeds JPEGs unchanged when possible, then lowers quality and dimensions only down to a readable floor. If that is not enough it reports the actual size and says the target was not met.

Can I combine several images into one PDF?

Yes. Select multiple files, reorder them with the arrows, remove any you do not need, and each image becomes one page in that order.

Is the PDF a normal, standards-compliant file?

Yes. It is a standard PDF 1.4 file with each JPEG embedded as an image on its own page. Nothing is truncated or padded to hit a number.
