A JPG is often what you have: a logo exported from a design app, a product photo, a headshot for a personal site. Converting it to a proper favicon ICO requires more than renaming the extension — you need the image resized, squared, and bundled at the six standard sizes that browsers and operating systems expect. Enhydra RPO handles all of that in one run.
Each output ICO embeds six pixel-square sizes — 16, 32, 48, 64, 128, and 256 px — so the OS picks the sharpest match for each context rather than scaling one size up or down. One practical tip before you convert: if your JPG is not already square, stack the crop tool alongside the ICO converter in Enhydra RPO so you can square up the source in the same pass. A non-square JPG going into ICO conversion will produce letterboxed or cropped icon sizes that look off in browser tabs.
Not every JPG converts into a recognizable icon. The constraint is brutal: at 16×16 px, you have 256 pixels to work with. What survives that reduction:
A portrait photograph or a scene with multiple elements will produce a muddy square at tab size. If your JPG logo has text alongside the symbol, the favicon should typically show only the symbol — crop to that element before converting.
JPG does not carry an alpha channel — there is no transparency in a JPG file by definition. When a JPG is converted to ICO, the background in the output is the original background color from the JPG itself: white, black, a brand color, or whatever the JPG showed.
If your logo was exported as JPG with a white background and you want a transparent favicon, the conversion chain to use is: first convert the JPG to PNG (use the JPG-to-PNG tool) with background removal if needed, then convert that PNG to ICO. The ICO format supports alpha transparency, and PNG carries it correctly into the ICO embed process.
For most logo-on-solid-color cases, the JPG background color simply becomes the icon background, which is perfectly workable — browser tabs show the favicon against a white or colored tab, and a matching or neutral background is fine.
Yes, strongly recommended. Stack Enhydra RPO's crop tool alongside the ICO converter and set a square aspect ratio. A non-square JPG produces letterboxed or cropped embedded sizes that look wrong in browser tabs and taskbars.
At least 256×256 px. The converter scales down to generate each embedded size; a larger source produces sharper results at 16 and 32 px. A 512×512 or larger square JPG is ideal.
Yes. Upload up to 200 JPG files; each gets its own multi-size ICO output, all packaged in a single ZIP download.
The 16×16 tab size reveals every detail problem. Use a simpler, higher-contrast source image — a single bold symbol reads far better than a complex logo at that size.
