Processing happens locally in your browser. The desktop app adds more formats, better performance on very large files, and advanced automation.
PNG to JPG converts PNG images to JPG — smaller files for email, web and anywhere a background-free image is fine. It runs locally through the unified Convert tool, so there is no upload and no queue.
PNG is lossless and supports transparency; JPG is much smaller but flattens transparency to a solid background. Pick JPG when file size wins, PNG when transparency or exact pixels matter.
How To Use PNG to JPG Offline
- Open PNG to JPG — Under Image Tools, or search "convert" with ⌘/Ctrl+K — it is the Convert tool set to JPG output.
- Drop your PNGs — Drag the batch in — Convert handles JPG, PNG, WebP, HEIC, TIFF, GIF and BMP input.
- Process — Each PNG becomes a .jpg in your output folder — ~/Documents/1FileTool by default.
- Optional: shrink further — Run the results through Compress Images to squeeze the JPGs even smaller.

Formats
| Input | Output | Notes |

Good to know
- Replace source is ON by default — it overwrites originals with no backup. Turn it off in Settings › General to keep both.
- JPG has no transparency — transparent PNG backgrounds become solid.
- JPG is lossy — for pixel-perfect output convert to WebP lossless or keep PNG.
- The free plan processes 8 files per calendar day.
Tips
- Screenshots and graphics with text often stay readable after conversion — but check fine lines before deleting the PNGs.
- If the goal is just a smaller file and you need transparency, WebP is a better choice than JPG.
- Batch it: drop the whole folder and let the background task bar track progress.
Frequently asked questions
What happens to transparency?
JPG cannot store transparency — transparent areas flatten to a solid background. Keep PNG or convert to WebP if alpha matters.
How much smaller is the JPG?
Usually a lot — PNG screenshots and graphics often shrink by half or more. The result card shows the exact size before and after.
Can I convert other formats to JPG?
Yes — the same Convert tool turns WebP, HEIC, TIFF, GIF and BMP into JPG, and converts between all of those formats.
Does it run offline?
Yes — conversion uses the bundled image engine entirely on your device.
