Screenshot for a report or email
1600×900 dashboard screenshot
- PNG
- 139.0 KB
- JPEG
- 83.8 KB
- WebP
- 40.7 KB
Best pick: WebP. WebP was 71% smaller than PNG. If the person opening it uses an older app, choose JPEG instead.

Step by step
How to save a clipboard image as a file
Four steps, about a minute. Every screenshot below is the real tool with a real test image.
-
Copy an image
Copy any image to your clipboard. Take a screenshot straight to the clipboard with Win+Shift+S on Windows or Cmd+Shift+Ctrl+4 on a Mac, or right-click an image in your browser and choose Copy image. Our test image is a 1600×900 dashboard screenshot.
-
Paste it into the tool
Click the box and press Ctrl+V, or Cmd+V on a Mac. If nothing happens, press Access Clipboard and allow the browser permission prompt. You can also drag an image file onto the box.
-
Pick a format
PNG is the default. Switch to WebP or JPEG from the menu and the size shows next to the Download button right away. Our test screenshot was 80.1 KB as a source file, came out as 139.0 KB as PNG, 83.8 KB as JPEG, and 40.7 KB as WebP.
-
Download the file
Auto-download is on by default, so the file is saved as soon as you paste and again each time you change the format. Untick it if you want to compare formats first, then press Download when you are happy. Files are named pasted_ followed by the date and time.
Real examples
What you get for common jobs
We pasted four test images into the tool and wrote down the file size it produced for each format. These are real results at the default quality, not estimates.
Full-screen capture for a document
2560×1440 full-screen capture
- PNG
- 266.1 KB
- JPEG
- 156.2 KB
- WebP
- 72.4 KB
Best pick: WebP. A bigger capture saves more in absolute terms: 193.7 KB less than PNG, without changing how it looks on screen.
Signature to place in a PDF
1200×500 signature, transparent background
- PNG
- 47.6 KB
- JPEG
- 29.5 KB
- WebP
- 18.4 KB
Best pick: PNG. PNG and WebP keep the transparent background. JPEG fills it with white, which shows as a box on a coloured page.
Icon or logo for a website
512×512 icon, rounded transparent corners
- PNG
- 259.0 KB
- JPEG
- 20.4 KB
- WebP
- 10.3 KB
Best pick: WebP. Use PNG when a platform insists on it, such as a favicon source. Otherwise WebP is the smallest and keeps the rounded corners clean.
Test images are generated flat-colour graphics, which is what most screenshots, logos, and signatures are. Photos behave differently: JPEG and WebP usually save far more on a photo than they do here.
Choosing a format
PNG, JPEG, or WebP?
The same 1600×900 screenshot, saved three ways. If you are unsure, start with WebP and switch to PNG or JPEG only if the place you are uploading it rejects the file.
| Format | Test file size | Best for | Watch out for |
|---|---|---|---|
| PNG | 139.0 KB | Screenshots, text, logos, anything that needs a transparent background | Re-encoding in the browser can make an already-optimized PNG larger. Our 80.1 KB source came out at 139.0 KB. |
| JPEG | 83.8 KB | Photos and anything that must open in every app, including old ones | No transparency. Clear areas are filled with white. |
| WebP | 40.7 KB | Web pages, chat, and email when the other side is a modern browser or app | A few older desktop programs cannot open it. Switch to JPEG or PNG for those. |

Troubleshooting
When something does not work
Ctrl+V does nothing
Check that you copied the picture and not a link or a file path. Click inside the paste box first so it has focus, then paste again.
The Access Clipboard button does not respond
Your browser may be blocking clipboard reads for this site. Allow the permission prompt, or paste with the keyboard instead. Chrome, Firefox, and Safari differ here.
It does not work on my phone
Mobile browsers ask for permission differently. Android and iPhone each need their own steps, and saving from the gallery is the fallback.
The PNG came out bigger than my original
The browser re-encodes the image and its PNG encoder is less aggressive than a dedicated optimizer. Choose WebP or JPEG to shrink the file.
Frequently Asked Questions
How do I use paste image to download on mobile?
Tap the Access Clipboard button to grant permission, then paste your image, or import it from your gallery or file manager if that button does not respond. Android and iOS handle this permission differently, which is covered in the guide to clipboard images on Android vs iPhone.
Why won't Ctrl+V paste my image?
The most common cause is that your clipboard does not actually contain image data, for example you copied a link instead of the picture itself. It can also be that the paste zone does not have focus yet, or that your specific browser applies stricter permission rules. See why clipboard paste behaves differently across browsers for the full breakdown.
Can I paste an image and convert it to another format?
Yes. Paste any image from your clipboard or drag and drop a file, then download it in PNG, JPEG, or WebP format. Conversion happens locally in your browser when supported.
Is PasteDownloadApp free?
Yes, completely free with unlimited downloads. No sign-ups, no watermarks, no hidden fees, and no usage caps.
Why is my downloaded file a different size than expected?
If you chose PNG as the output, the browser's built-in encoder is not as aggressive as a dedicated PNG optimizer, so an already-optimized PNG can come out larger, not smaller. JPEG and WebP use a fixed 92% quality setting that produces a real, tested reduction. Both effects are shown with actual before-and-after numbers in why re-saving a PNG can get bigger.
Does this work if I copy an image from a PDF?
It depends on your PDF viewer. If it lets you right-click an embedded image and choose Copy Image, that places real image data on your clipboard and it pastes normally here. Some viewers only copy a text or vector selection, which will not paste as an image. Taking a screenshot of the PDF page always works as a fallback.
How does the browser-based processing work?
The tool uses the browser's Clipboard API to read image data and the Canvas API for format conversion, all processed on your device.
