How do I use my phone as a magnifying glass?

Press "Start magnifier" and allow the camera. The rear camera opens when your device has one. Hold the phone over the text, use the "Zoom" slider (or the plus and minus buttons) until it is big enough, and press "Freeze frame" if you want the picture to stand still while you read.

What is the difference between camera zoom and digital zoom?

If the camera offers its own zoom (common in Chrome on Android), the slider uses it and the range comes from the camera. Otherwise the page enlarges the middle of the camera image, from 1× up to 8×, and you can drag the picture to move around. Digital zoom cannot add detail the camera did not capture, so for tiny print move closer or add light first.

What do the reading filters do?

"High contrast" turns the picture black and white and doubles the contrast, which makes faint print stand out. "Invert" swaps light and dark, and "High contrast inverted" does both, giving white text on black. The same filter is applied to the picture you save with "Take snapshot".

Can I use the torch and save a picture?

Where the camera allows it (Chrome on Android), a "Torch on" button appears to light the page; if it does not, the page says the torch is not available. "Take snapshot" makes a PNG of what you see, zoom and filter included, with its longest side capped at 1,920 pixels. Press "Download PNG" to save it as a file named like magnifier-20261008-143015.png.

Is my camera picture uploaded or recorded?

No. The camera starts only after you press "Start magnifier", the picture is drawn and filtered in your browser tab, and nothing is recorded or sent. The camera stops when you press "Stop camera", when you switch to another tab and when you leave the page.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.

Tips for reading small print

Good light matters more than zoom. Turn on a lamp, or the torch where it is available, and keep your hand's shadow off the page.
If the picture is blurry, move the phone a little further back and then zoom in. Most phone cameras cannot focus very close.
Press "Freeze frame" to stop the picture moving so you can read it comfortably, then "Unfreeze" to carry on.
On a computer this uses your webcam, which is rarely suited to close-up reading.

🔍 Camera pictures stay in your browser tab. Nothing is uploaded, and the camera stops when you press "Stop camera", switch tabs or leave the page.

How It Works

The page opens the rear camera, draws the part of each video frame you have zoomed into onto a canvas, and applies the reading filter on top.

1
Start the camera
Press "Start magnifier" and allow the camera. The rear camera is used when the device has one.
2
Zoom and filter
Use the "Zoom" slider or the plus and minus buttons, and pick "High contrast", "Invert" or "High contrast inverted" for easier reading. Drag to move around when digital zoom is in use.
3
Freeze or light
Press "Freeze frame" to hold the picture still. Where the camera supports it, "Torch on" lights the page.
4
Save a snapshot
Press "Take snapshot", then "Download PNG". The filter you chose is included in the saved picture.

Camera pictures stay in your browser tab and are never uploaded. The camera stops when you press "Stop camera" or leave the page.
