How do I convert ICO to PNG without losing image quality?
+
Upload your ICO file and the converter applies format-aware quality optimization for PNG. For lossless PNG (PNG, TIFF, BMP) every pixel is preserved; for lossy PNG (JPG, WebP) you can tune the quality factor before download.
Does ICO to PNG conversion preserve transparency?
+
Transparency survives when PNG is PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background. If you need transparency in the result, target a transparency-aware PNG instead of PNG=JPG.
Will my color profile (sRGB / Adobe RGB / CMYK) survive ICO to PNG?
+
Embedded ICC color profiles are read from ICO and re-attached to the PNG output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB, which keeps colors consistent across most modern displays.
What about EXIF metadata when converting ICO to PNG?
+
Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during ICO → PNG when both formats support metadata. Use the privacy option to strip metadata before download if you need to share images without geolocation.
Can I batch-convert many ICO files to PNG at once?
+
Yes — drag multiple ICO files into the upload zone and we queue them in parallel. Free users get 100 MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
How does ICO to PNG compare to Photoshop / GIMP for the same task?
+
For straight format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same output quality. The difference is parallel batch handling — desktop apps open one file at a time; we accept a batch.
What resolution will my PNG file have?
+
Default is 1:1 — your PNG keeps the pixel dimensions of the source ICO. If you need to resize as part of the conversion, use /resize-image/ after conversion, or chain it with the /image-resize/ utility.
How small can the PNG get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically gets the PNG 60-80% smaller than ICO with no visible difference at normal viewing distance. For lossless PNG (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Are my ICO files private during conversion?
+
Yes — uploaded ICO files are processed in isolated workers and deleted within minutes. We never read, store long-term, or share the pixel data. The full retention window is documented at /privacy/.
Does the ICO to PNG converter work for very large images (50MP+)?
+
Yes for free up to 100 MB. Premium handles larger inputs (300 MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams rows so memory use scales with row count, not total pixel count.
Why is my converted PNG bigger or smaller than I expected?
+
A ICO with strong existing compression (lossy JPG) often grows when re-encoded to lossless PNG (PNG, TIFF). A lossless ICO often shrinks dramatically when going to JPG / WebP. The ratio depends on image content — photos compress differently from line art.
Can I use the converted PNG commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source ICO). We add no watermark, no metadata stamp, and claim no licence over the PNG output.
