Screenshot to JPG: what the conversion actually does
Screenshots are saved as PNG by macOS, Windows and most phones, which is why a folder of them is surprisingly large and why some upload forms reject them. Converting to JPG shrinks each one by 70-90% and produces a file that every form, email client and document editor accepts.
How to convert Screenshot to JPG
- 1Drop your screenshots above — PNG, HEIC or anything else your device saved.
- 2Use quality 92 or higher if the screenshot contains text, which most do.
- 3Convert and download, individually or as one ZIP.
Why your screenshots are PNGs
PNG is the sensible default for a screenshot: it is lossless, so text stays exactly as rendered. It is also why a 1920 by 1080 capture of a spreadsheet can be 900 KB and a Retina capture several megabytes.
- macOS saves to PNG by default (Command-Shift-3 or 4).
- Windows Snipping Tool and Print Screen produce PNG.
- iPhone and iPad screenshots are PNG even when the camera is set to HEIC.
- Android varies by manufacturer, but PNG is the common default.
Quality matters more here than for photos
JPEG compression works by discarding high-frequency detail, and a screenshot is almost entirely high-frequency detail — every letter is a hard black-on-white edge. That is why a quality-70 JPG of a photograph looks fine and a quality-70 JPG of a screenshot looks smeared, with grey halos around the text.
Use 92 or above for anything with words in it. You still get a large saving over the PNG, and the text stays sharp.
| Screenshot content | Suggested quality | Typical result |
|---|---|---|
| Text, code, spreadsheets | 92-97 | Sharp text, 60-80% smaller than PNG |
| App UI with icons | 88-92 | Clean, 75-85% smaller |
| A photo or video frame | 82-90 | Indistinguishable, 85-95% smaller |
| A chart or diagram | Keep as PNG | JPEG ringing on thin lines is obvious |
Stop the size problem at the source
- macOS: run 'defaults write com.apple.screencapture type jpg' then 'killall SystemUIServer' in Terminal to capture JPG directly.
- Windows: the Snipping Tool's save dialog offers JPG in the file-type list.
- iPhone: screenshots stay PNG; converting afterwards is the only option.
- Crop before you convert — half a screenshot is half the pixels, and cropping costs no quality at all.
Privacy
Nothing is uploaded. The file is decoded and re-encoded by your own browser using the Canvas API, so the image never leaves your device and there is no queue, no size cap and no account.
Three mistakes to avoid
Converting at quality 70 to hit a size limit
Crop or resize instead. Dropping the quality on text is the most visible thing you can do to a screenshot.
Forgetting what is in the screenshot
Conversion keeps every pixel visible in the original, including tabs, notifications and account names. Crop or redact before sharing.
Assuming JPG always wins
For a screenshot of a simple diagram or a mostly-white page, PNG can be both smaller and sharper. Compare the two.
