JPEG to ICO Conversion FAQ
Does the JPEG to ICO converter keep transparency?
+
When ICO supports an alpha channel (PNG, WebP, GIF) and the original JPEG had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Can I batch-convert JPEG images to ICO?
+
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.
Will the converted ICO have the same dimensions as my JPEG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the ICO resize tool after the conversion finishes.
Is my JPEG image private when I convert it?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded JPEG and the resulting ICO are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
Why is my converted ICO file larger than the original JPEG?
+
If ICO is lossless and JPEG was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Can I convert JPEG to ICO on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert JPEG to ICO from any iPhone or Android device without using local storage.
