How to convert ICO to PNG
- Step 01
Add your ICO file
Drop one or many ICO files onto the converter, or browse from disk. Stay within the on-device size limits shown under the drop zone — oversized files are rejected so your tab does not freeze.
- Step 02
Tune and convert
Set quality if the PNG encoder offers it, then start the conversion. Pixels are processed on this device — nothing is uploaded.
- Step 03
Download PNG
Download your new PNG file immediately. Multiple outputs pack into a single ZIP archive.
Why convert ICO to PNG
ICO is a Windows / favicon format known for packs multiple icon sizes into one file, while PNG is a lossless raster format valued for pixel-perfect quality plus full alpha transparency. Converting ICO to PNG is the practical fix when a workflow expects PNG — for example logos, screenshots, UI graphics, and graphics with sharp edges — but your file still lives as ICO. Browser Convert performs that swap entirely in your browser so the pixels never upload to a remote converter.
When to use this tool
- A tool, form, or teammate asked for PNG, but you only have ICO.
- You are optimizing for logos, screenshots, UI graphics, and graphics with sharp edges instead of staying in ICO.
- ICO’s limits (awkward for general image editing and sharing) are getting in the way, and PNG handles that job better.
Good to know
- Output characteristics follow PNG: pixel-perfect quality plus full alpha transparency.
- Source quirks still apply — ICO is limited by awkward for general image editing and sharing, and conversion cannot invent missing data.
- If you care about crisp UI text, prefer lossless destinations or higher quality settings.
- Browser limit: about 40 MB per image, up to 20 files per batch. Very large dimensions are scaled down automatically.
- Need a bigger file? For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
File size limits for ICO to PNG
Browser limit: about 40 MB per image, up to 20 files per batch. Very large dimensions are scaled down automatically.
Why there is a limit
Images are decoded into memory on your device. Huge files can freeze or crash the tab, so we cap size to keep conversions reliable without uploading anything.
If your file is too large
For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
ICO to PNG FAQ
Common questions about converting ICO files to PNG.
Is this ICO to PNG converter free?
Yes. Browser Convert does not charge for ICO → PNG, add watermarks, or require an account.
Will ICO to PNG keep image quality?
PNG is well suited to preserving detail for this path. Still, starting from a soft or tiny ICO cannot create sharper pixels than you began with.
Does PNG support transparency from ICO?
PNG can store transparency. If your ICO had no alpha channel, the result stays opaque unless you edit it afterward.
Is ICO to PNG conversion private on Browser Convert?
Yes. Your ICO icon is processed in the browser. We do not upload the file to convert it, which is the main difference from typical online converters.
Are there file size limits for ICO to PNG?
Yes. Browser Convert accepts about 40 MB per file, with up to 20 files queued at once. Images are decoded into memory on your device. Huge files can freeze or crash the tab, so we cap size to keep conversions reliable without uploading anything. Very high-resolution images may be downscaled (about 40 megapixels / 8192px on the longest edge) so canvas encoding stays stable. If your file is larger, For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
Can I convert several ICO files to PNG at once?
Yes. Queue up to 20 ICO files and convert them in one pass. When finished, download the batch as a ZIP. Very large batches may need to be split so your browser stays responsive.
