Good to know: your images stay here only while this page is open. If you refresh or close it, they are cleared. When you are done, press Full screenshot, then Download PNG to keep your result.

🔒 Your images never leave your browser. Nothing is uploaded or stored.

Combine screenshots into one image, free

ShotMax puts many screenshots on one canvas so you can compare them side by side, then saves them as a single full-resolution PNG. It is handy for design reviews, bug reports, before/after checks, client proofs and study notes.

How it works

Add your screenshots with Ctrl+V, drag & drop, or Add files.
Compare them in a 1 to 5 column grid. Click any image to zoom and pan at original quality.
Save with Full screenshot: one PNG with all images, optional numbers and a background colour you pick.

Why ShotMax

Original quality. Every image keeps its own pixels. Nothing is compressed.
Private by design. It runs in your browser. No upload, no account, no stored images.
Fast and simple. Up to 50 images at once, on desktop or phone.
Free. No watermark and no sign-up.

Questions

Are my screenshots uploaded anywhere?

No. Everything happens inside your browser tab. When you close or reload the page, the images are gone. Save your result with Download PNG first.

Does it reduce image quality?

No. Images are placed at their original size and saved as PNG. Only if the combined picture would be larger than your browser can draw (very large collections) is it scaled down, and ShotMax tells you when that happens.

How many images can I add?

Up to 50 at a time.

Does it work on a phone?

Yes. Tap the box to pick screenshots from your gallery. Ctrl+V is for computers.

The Copy button does not work. Why?

Some browsers do not allow copying images to the clipboard. Use Download PNG instead.
