Full Resolution

Convertio extracts the highest resolution image from your ICO container and converts it to PAL — preserving maximum detail.

Your Files Stay Safe

ICO files are erased from servers right after conversion completes. PAL downloads are available for 24 hours, then automatically removed.

Bulk Conversion

Need to convert dozens of ICO files? Upload them all and batch-convert to PAL — much faster than processing one at a time.

About formats

ICO is the icon file format for Microsoft Windows, introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.

PAL is a 16-bit per pixel interleaved YUV image format that stores color information using a luminance-chrominance model rather than direct RGB values. Each pixel pair is packed into four bytes using the UYVY byte ordering — U (Cb), Y0, V (Cr), Y1 — where two adjacent pixels share a single set of chroma (color difference) samples while each retaining its own luminance (brightness) value. This 4:2:2 chroma subsampling halves the color resolution horizontally with negligible perceptual impact, since human vision is far more sensitive to brightness variations than color detail. The format traces its conceptual roots to analog broadcast television standards developed during the 1960s and 1970s, where separating luminance and chrominance enabled backward-compatible color transmission alongside existing monochrome signals. In digital imaging, 16-bit YUV serves as a common intermediate representation for video capture hardware, frame grabbers, and image processing pipelines that work in the YCbCr color space internally before converting to RGB for display. One advantage is bandwidth efficiency: at 16 bits per pixel, UYVY requires roughly two-thirds the data of uncompressed 24-bit RGB while preserving virtually identical perceived quality, making it well suited for high-throughput video capture and real-time image processing applications. The format's direct correspondence to how video hardware captures and outputs data provides another practical benefit — many capture cards and camera sensors natively produce UYVY data, so storing it in PAL form avoids an unnecessary color space conversion step that would add latency and introduce rounding artifacts.

Frequently Asked Questions

Why convert ICO to PAL?

PAL produces interleaved YUV data from your icon — used in video processing and broadcast workflows that require YUV color space input.

Which apps support PAL files?

You can open PAL files with video processing tools, ImageMagick. Free alternatives are available for every platform.

Can I convert multiple ICO files at once?

Yes — Convertio supports batch uploads. Queue several ICO files and convert them all to PAL format in a single session without repeating steps.

Does ICO to PAL keep transparency?

If PAL supports transparency (like PNG or WEBP), the alpha channel from your ICO is preserved. Formats without transparency support fill with a solid background.

Are my files safe during conversion?

Convertio uses encrypted connections for all transfers. Your ICO uploads are deleted immediately after conversion, and PAL downloads are removed within 24 hours.

Is the conversion process fast?

ICO to PAL conversion usually finishes in a few seconds. Larger files may take slightly longer, but the cloud-based processing keeps things efficient.
