Best JPG to PDF settings
Use practical presets to balance image quality, readability, and file size.
Pick the destination first
The best settings depend on what the PDF has to survive after export. A file for email should be small enough to send. A file for print should preserve detail. A file for an application portal should match the requested page size and stay safely below the upload limit. Start with the destination, then adjust DPI, compression, layout, and margins.
Quick settings matrix
| Use case | DPI | Compression | Page setup | Best habit |
|---|---|---|---|---|
| 120-144 | Medium-high | Letter or A4, 1-up | Export a sample and keep 10-20% below the mail limit. | |
| Upload form | 144-180 | Medium | Use the required paper size | Check the portal's limit before converting the full batch. |
| 240-300 | Low-medium | 1-up, Fit, sensible margins | Preserve edges and avoid aggressive compression. | |
| Receipt bundle | 144-180 | Medium | 2-up if readable | Group receipts by date and review totals at actual size. |
| Archive | 200-240 | Medium-low | Consistent size and orientation | Favor future readability over the smallest possible file. |
What each setting really changes
DPI controls how much image detail is placed into the PDF. Lower DPI reduces size but can soften small text. Compression controls how much visual data is discarded. More compression can shrink photos well, but screenshots and text-heavy images may show rough edges. Fit keeps the entire image visible. Fill can remove borders but may crop important edges. Margins help printed pages and make phone photos feel less cramped.
Example starting points
For a ten-page receipt PDF made from phone photos, start with 144 DPI, medium compression, Strip metadata on, and 2-up only if the totals remain readable. For a two-page ID or application upload, use A4 or Letter as required, 180 DPI, medium compression, and Fit. For photo sheets meant to print, use 240 or 300 DPI, low-medium compression, 1-up layout, and a white background.
Change one variable at a time
If the PDF is too large, lower DPI first from 200 to 180 or 144. If it is still too large, increase compression slightly. If it is still too large after that, consider 2-up layout or splitting the document. Changing DPI, compression, page size, and layout all at once makes it hard to know which setting helped or harmed the output.
Settings that are easy to overlook
- Strip metadata: Good default for privacy and small size. It removes camera information that usually does not help the PDF.
- Background color: Use white for documents. Dark backgrounds make sense only for images intentionally designed that way.
- Orientation: Set portrait or landscape before exporting, then rotate individual pages that still look wrong.
- Images per page: Useful for receipts and contact sheets, risky for small text.
Recommended testing routine
- Add two representative images, not the whole batch.
- Export with your planned settings.
- Open the PDF at 100% zoom and check the smallest text.
- Check file size against your real limit.
- Only then process the full set.
Why there is no universal perfect setting
A receipt, a passport photo, a screenshot, and a print handout all reward different choices. A low-size profile can be excellent for email and poor for print. A high-DPI profile can be excellent for archiving and too large for a portal. Treat the recommendations on this page as starting points, then verify the final PDF against the real destination.
