Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.
Fix a photo for an upload form →Favicon generator
Resize an image into the standard set of favicon sizes.
A favicon isn't one image, it's a set — the browser tab wants a small one, an iOS home-screen shortcut wants a large one, and Android wants something in between. Drop in a single square image and get back the whole standard set at once.
How Favicon generator works
- Drop your file into the tool, or click to browse.
- Everything runs in your browser — no upload, no server, no waiting.
- Download your result straight to your device.
Good to know: Sizes generated: 16, 32, 48, 96, 180, 192, and 512 pixels. Start from a square image — a rectangular one will be squashed to fit — and keep the design simple, because at 16 pixels anything detailed turns to mush.
Common questions
What size should my source image be?
Square, and at least 512x512, so the largest size is generated from real detail rather than upscaled. Simple, high-contrast shapes survive the shrink to 16 pixels; fine detail and small text do not.
