PNG to ICO Transformation FAQ
How do I convert PNG to ICO without losing image quality?
+
Upload your PNG file and the converter applies format-aware quality optimization for ICO. For lossless ICO (PNG, TIFF, BMP) every pixel is preserved; for lossy ICO (JPG, WebP) you can tune the quality factor before download. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel. A single ICO holds several renderings of the same icon at different sizes — 16x16 through 256x256 — so the OS can pick the sharpest one.
Does PNG to ICO conversion preserve transparency?
+
Transparency survives when ICO 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 ICO instead of ICO=JPG. ICO is the Windows icon format, and it is the only image format browsers will accept at /favicon.ico.
What about EXIF metadata when converting PNG to ICO?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the ICO. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.
Can I batch-convert many PNG files to ICO at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What resolution will my ICO file have?
+
Default is 1:1 — your ICO keeps the pixel dimensions of the source PNG. If you need to resize as part of the conversion, use /resize-image/ after conversion, or chain it with the /image-resize/ utility.
Are my PNG files private during conversion?
+
Yes. Uploaded PNG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted ICO are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why is my converted ICO bigger or smaller than I expected?
+
A PNG with strong existing compression (lossy JPG) often grows when re-encoded to lossless ICO (PNG, TIFF). A lossless PNG often shrinks dramatically when going to JPG / WebP. The ratio depends on image content — photos compress differently from line art. PNG is a poor photograph format: a photo saved as PNG is routinely five to ten times larger than the same image as JPG or WebP. ICO is not a general image format: it is square, small, and no photo editor treats it as a first-class working file.
Can I use the converted ICO commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source PNG). We add no watermark, no metadata stamp, and claim no licence over the ICO output.
