When the JPG to PDF Converter seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Photos look soft when printed
Use sources of at least 150-300 DPI at the printed size; tiny JPGs cannot fill a page.
Images are cropped at page edges
They do not match the page ratio - fit images to the page or choose a matching size.
Pages are out of order
Arrange the sequence before converting; PDF pages follow your order exactly.
The PDF is too large to email
Compress the JPGs before conversion, or use a shared link for the final document.
Orientation keeps flipping
Set portrait or landscape deliberately; mixed content may need per-page settings in an editor.
White borders everywhere
Page size is larger than the image ratio - pick a closer page size or scale images up.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Mixing portrait and landscape shots without orientation rules
- Using low-resolution JPGs and getting soft prints
- Sending pages in the wrong order
- Creating an enormous PDF from full-resolution originals
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Can several JPGs go into one PDF?
Yes - each image becomes a page in the order you arrange them.
What resolution do the images need?
Around 150-300 DPI at final print size for crisp output.
Does the PDF compress my photos?
The images are embedded as supplied - compress the JPGs beforehand if weight matters.
Are my files uploaded?
No - the PDF is built locally in your browser.
