How to use it
- 01Choose up to 8 supported images. File contents are checked instead of trusting the extension.
- 02Choose PNG or JPG. Open Optional settings only when you need a quality, fill-color or size adjustment.
- 03Convert, review dimensions and actual file size, then download successful results.
Choose this conversion for the right reason
An ICO can contain several embedded sizes. This tool selects the largest directory entry and decodes supported PNG-backed or uncompressed 24/32-bit DIB artwork. Smaller entries and uncommon variants are not combined into an output set.
Files are processed one at a time in a worker to limit peak memory. Invalid or unsupported images are reported individually. Conversion changes format; it does not guarantee compression, remove a background or recreate missing source detail.
Practical check: Compare the selected icon’s dimensions and edges; a larger canvas cannot recreate detail absent from it.
Useful details and limits
Uses the largest embedded icon. Supports PNG-backed and uncompressed 24/32-bit DIB icons; other variants may fail. Limits: 20 MB per file, 40 MB input per batch and 120 MB combined results. General decoding is capped at 20 million pixels and 16,000 pixels per side. Metadata and color profiles are not preserved. Originals are not changed. A failed file receives its own error and does not stop the other conversions.
Questions about this tool
Should I choose PNG or JPG?
PNG keeps supported transparency and sharp graphic edges. JPG is lossy and fills transparent pixels with the chosen background color. Choose a format accepted by the recipient and review actual size.
What should I check before using the converted file?
Compare the selected icon’s dimensions and edges; a larger canvas cannot recreate detail absent from it.
Are my images uploaded or stored?
No. Files, previews, conversion and ZIP creation remain on your device. A codec may load from Tool Fera when needed, but your image bytes are not sent with that request.
Understand the workflow
- ICO files and favicon sizes: what an icon contains
Understand ICO containers, embedded sizes and PNG-backed icons. Prepare square artwork and check the exact variant your application or favicon workflow accepts.
- Image dimensions versus file size: pixels are not megabytes
Understand pixels, bytes, aspect ratio and compression. Choose resizing or quality changes for a real upload requirement and compare the final image.
