How to Save a Screenshot as a JPG or JPEG

A screenshot is not a JPG: Windows, Mac, iPhone and most Android phones save it as a PNG. To save a screenshot as a JPEG, either use Save As and pick JPEG (Snipping Tool or Paint on Windows), switch the Mac's capture format to JPG, or convert the screenshot to JPG in your browser. Here is each route, step by step, for every device.

Screenshot to JPG by device: quick steps

Is a screenshot a JPG?

No — and this catches people out constantly. Windows, macOS, iPhone and iPad all capture to PNG, and so do most Android phones. PNG is a sensible default for a screenshot because it is lossless: every pixel of text and every UI edge is stored exactly as it was drawn. The cost is size. A 1920 × 1080 capture of a spreadsheet is often 1 MB or more as a PNG and a few hundred KB as a JPG, and a Retina or high-DPI capture can be several megabytes.

That is why upload forms with a 2 MB cap, email attachments and chat apps all start complaining about screenshots specifically. The picture is not unusually complicated; the format is simply not built for size.

Print Screen to JPG on Windows

Pressing Print Screen copies the screen to the clipboard rather than saving a file. Windows key + Print Screen saves a PNG into Pictures > Screenshots, and Windows key + Shift + S opens the Snipping Tool for a selection. In every case you end up with a PNG.

Three ways to get a JPG: paste the clipboard into the Snipping Tool or Paint and use Save As, where JPEG is in the file-type list; press Ctrl + V on the paste image to JPG page and click Save as JPG; or save the PNG as normal and convert it. Pasting is the quickest for a single capture, and converting is the only option once the screenshots are already sitting in a folder.

How to save a snip as a JPEG

In the Snipping Tool, click the save icon (or Ctrl + S), open the "Save as type" list and pick JPG. Windows 11 remembers the last type you chose. If you snipped with Windows + Shift + S and never opened the tool, the snip is only on the clipboard — paste it into the paste-to-JPG tool or Paint to turn it into a file.

Why Are Screenshots So Large?

Screenshots use PNG (Portable Network Graphics) format because it's lossless — every pixel is perfectly preserved. This is great for UI elements, text, and sharp edges, but it creates unnecessarily large files:

Converting to JPG typically reduces file size by 80-95% with no visible quality difference for most screenshots. The pixel count is fixed by your screen, not by a DPI setting — see what DPI a computer screen really is.

The Fastest Method: Online Converter

The quickest way to convert any screenshot to JPG — regardless of your device:

1. Open our PNG to JPG converter
2. Drag & drop your screenshot(s)
3. Set quality to 85–92% — use the higher end when the screenshot is mostly text, so letters stay crisp
4. Click Convert and download

This works on phones, tablets, and computers — no app installation needed. Your files never leave your device.

Mac: Change Default Screenshot Format

You can make your Mac save screenshots as JPG automatically:

1. Open Terminal (Applications → Utilities → Terminal)
2. Type: defaults write com.apple.screencapture type jpg
3. Press Enter, then type: killall SystemUIServer

From now on, all screenshots (⌘+Shift+3 and ⌘+Shift+4) will save as JPG. To revert: replace jpg with png in the command.

Note: macOS has no quality setting for JPG screenshots. If you need a smaller file or sharper text, take the screenshot as PNG and choose the quality yourself in the screenshot to JPG converter.

Windows: Convert Screenshots

Windows screenshots (Win+PrintScreen) save as PNG to your Pictures/Screenshots folder. Options to convert:

• Snipping Tool — In Windows 11, open your screenshot in Snipping Tool and use "Save As" → select JPEG format
• Paint — Open the PNG in Paint, File → Save As → JPEG
• Batch convert — For multiple screenshots, use our batch PNG to JPG converter

iPhone & iPad

iOS screenshots save as PNG. To convert:

• Shortcuts app — Create a shortcut that converts selected photos to JPG and saves them
• Online converter — Open our converter in Safari, tap the upload area, and select screenshots from your photo library

Android

Most Android phones save screenshots as PNG (some newer Samsung devices use JPG). To convert:

• Open our converter in Chrome and select screenshots from your gallery
• Samsung Galaxy phones have a Screenshot format option (JPG or PNG) under Settings → Advanced features → Screenshots and screen recordings; most other Android phones have no such setting

Chromebook

Ctrl + Show windows captures the full screen and Ctrl + Shift + Show windows captures an area; ChromeOS saves both as PNG in your Downloads folder by default. There is no JPG option, so open the screenshot to JPG converter in Chrome, pick the files from Downloads and save the JPGs back to the same folder.

When to Keep Screenshots as PNG

JPG isn't always the best choice. Keep PNG when:

• You need pixel-perfect text — Bug reports, code screenshots, UI documentation
• The image has transparency — Some screenshot tools capture transparent backgrounds
• You'll be editing further — PNG preserves quality through multiple edits
• Filing a legal/compliance record — Lossless format is important for evidence

For everything else — email, chat, social media, form uploads — JPG is the better choice.

Batch Converting Multiple Screenshots

If you take a lot of screenshots (tutorials, documentation, testing), batch conversion saves hours:

1. Select all PNG screenshots in your folder
2. Drag them into our converter
3. Set quality to 85%
4. Convert all and download as ZIP

Screenshot still rejected by an upload form after converting? The file type not supported guide and the Google Drive unsupported file type fix cover the other causes, and compress to an exact size gets it under a size limit.
