How to Convert Screenshots to JPG on Any Device

Government forms, job applications, insurance portals — they all ask you to upload a JPG. Your screenshot is a PNG. Here's every method to fix this, on every platform, in under a minute.

Why Are Screenshots PNG by Default?

Screenshots are saved as PNG for a good reason: PNG is lossless, which means it preserves text, UI elements, and sharp edges perfectly. JPG compression would make text in screenshots look blurry and create artifacts around buttons and icons. PNG maintains pixel-perfect quality for these types of images.

The problem is that PNG files are much larger than JPG, and many upload forms have strict file size limits or only accept JPG format. A full-screen screenshot can be 1-3MB as PNG but only 150-400KB as JPG — small enough to upload anywhere.

Method 1: Convert Online (Fastest — Works on Everything)

The quickest method on any device — phone, tablet, Mac, PC:

1. Take your screenshot normally
2. Go to PNGtoJPG PNG to JPG converter
3. Drop your screenshot PNG onto the converter
4. Click "Convert All"
5. Download your JPG screenshot

The conversion takes 2-3 seconds. The resulting JPG is typically 60-80% smaller than the original PNG and looks identical for practical purposes.

Method 2: Windows — Save Screenshots as JPG Directly

Windows offers multiple ways to take JPG screenshots without converting afterward:

Using Paint

1. Take screenshot with Print Screen (PrtSc) key
2. Open Paint (search "paint" in Start menu)
3. Paste with Ctrl+V
4. File → Save as → JPEG picture

Using Snipping Tool

1. Open Snipping Tool (Win + Shift + S)
2. Take your screenshot
3. Click the notification that appears, or open Snipping Tool app
4. File → Save As → change file type to JPEG

Method 3: Mac — Convert Screenshot to JPG

Using Preview (Built-in)

1. Take screenshot (Cmd+Shift+3 for full screen, Cmd+Shift+4 for selection)
2. Open the screenshot PNG in Preview
3. File → Export
4. Change Format to JPEG, adjust quality
5. Save

Change Mac Screenshot Default Format

To make all future Mac screenshots save as JPG by default:

1. Open Screenshot app (Cmd+Shift+5)
2. Click "Options"
3. Scroll to "Save to" → then look for format options
4. Or via Terminal: defaults write com.apple.screencapture type jpg

Method 4: iPhone — Screenshot to JPG

iPhone screenshots are saved as PNG to the Camera Roll. To get a JPG version:

• Easiest: Open the screenshot in Photos → Share → Save as File → choose a location and it saves as JPG
• Online converter: Upload the PNG screenshot to PNGtoJPG from Safari and download as JPG
• Change camera settings: Settings → Camera → Formats → Most Compatible makes photos (not screenshots) save as JPG, but screenshots remain PNG regardless

Method 5: Android — Screenshot to JPG

Most Android devices save screenshots as PNG. To convert:

• Open the screenshot in Google Photos → tap the three-dot menu → try "Save a copy" (some versions offer format selection)
• Use the online converter in Chrome — go to PNGtoJPG, select the screenshot from your Downloads folder, convert and save
• Some Android manufacturer cameras have screenshot format settings — check Camera app Settings

How Much Does Converting Screenshot PNG to JPG Save?

Screenshot Type	PNG Size	JPG (85%)	Savings
Full desktop screenshot (1920×1080)	1.8 MB	380 KB	79%
Mobile screenshot (1080×2340)	900 KB	210 KB	77%
Browser window partial	450 KB	95 KB	79%
Dark mode screenshot	380 KB	72 KB	81%

Will the JPG Screenshot Look Worse?

At 85% quality or higher, the visual difference between PNG and JPG screenshots is minimal for most uses. The main visible difference is that tiny text and sharp UI elements might show very slight JPG artifacts at very close inspection. For practical uses like submitting forms, sharing screenshots, or uploading to portals, the converted JPG looks identical.

If you need a screenshot for documentation where pixel-perfect text quality is critical, keep it as PNG. For everything else, JPG at 85-90% quality is perfectly fine.

Batch Convert Multiple Screenshots

Need to convert a folder full of PNG screenshots? PNGtoJPG supports batch conversion — select all your PNG screenshots at once (up to 50), convert everything, and download as a ZIP file. The whole process takes under a minute regardless of how many screenshots you have.
