JPEG to ICO Conversion FAQ
How do I convert JPEG to ICO without losing image quality?
+
Upload your JPEG file, then our converter applies format-aware quality optimization for ICO output. For lossless formats (PNG, TIFF, BMP) we preserve every pixel; for lossy formats (JPG, WebP) you can tune the quality factor before download.
Can I get transparency once the image is ICO?
+
The ICO format supports it, but the conversion cannot invent it. A JPEG has no alpha channel, so every pixel including the background arrives fully opaque. Run /image-removebackground/ afterwards to cut the subject out — then the alpha channel ICO provides has something to store. ICO lets one file serve a taskbar, a file listing, a desktop shortcut and a browser tab without any of them looking resampled.
Does converting JPEG to ICO restore the quality that was lost?
+
No. The compression artefacts already baked into the JPEG are ordinary pixel data now, and ICO preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It is still worth doing before editing, because further edits will not stack a second generation of loss on top. JPEG shares every JPG limitation — no alpha, generational loss on re-save — with the added nuisance of software that treats the two extensions differently.
Will my CMYK colour survive the conversion to ICO?
+
It is converted to sRGB, because ICO has no CMYK mode. For screen use that is exactly what you want. For commercial print it is not — the gamut shift changes how saturated colours reproduce on press, so send the printer the original JPEG rather than the ICO. ICO is not a general image format: it is square, small, and no photo editor treats it as a first-class working file.
What about EXIF metadata when converting JPEG 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 hundreds of JPEG 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 and dimensions will my ICO file have?
+
Default behaviour is 1:1 — your ICO output has the same pixel dimensions as the source JPEG. Use a separate /resize-image/ step after conversion if you need to downscale or upscale as part of the workflow.
How small can the ICO file get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source JPEG with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Are my JPEG files private during conversion?
+
Yes. Uploaded JPEG files are processed on our own servers and are never viewed or shared. Uploads and converted images are deleted automatically about 24 hours after conversion. The full privacy policy is at /privacy/.
