JPEG to ICO Conversion FAQ
How do I convert a JPEG image to ICO?
+
Drop your JPEG image into the upload area. PDF.to re-encodes the pixels into the ICO container and gives you the new file in seconds. No account is needed.
Will the JPEG to ICO conversion lose detail or sharpness?
+
If ICO is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If ICO is lossy (JPG, WebP, JPEG), we use a high default quality setting that is visually indistinguishable from the source for almost all images.
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.
Does it preserve EXIF, color profile, and DPI from my JPEG file?
+
ICC color profiles and DPI tags are preserved when ICO supports them. EXIF metadata (camera, GPS, timestamps) is stripped by default for privacy; turn it on in PRO if you need it.
Can I convert a vector JPEG to a raster ICO (or vice versa)?
+
Yes. Vector-to-raster conversions rasterize at a sensible default resolution (typically 2× display); you can override the DPI in the options panel. Raster-to-vector is best-effort tracing and works best on logos and line art, not photographs.
What is the largest JPEG image I can convert to ICO?
+
Free accounts: up to 100 MB or 50 megapixels per image. PRO accounts: up to 5 GB and 1 gigapixel per image, which covers large scans and panoramas.
Can I batch-convert JPEG images to ICO?
+
Yes — drag a folder of JPEG files onto the page. Each is converted independently and zipped into a single download when done.
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 are encrypted in transit, the conversion job runs on an isolated worker, and the original JPEG plus the resulting ICO are deleted within an hour.
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.
Does the JPEG to ICO converter handle animated images?
+
If JPEG is animated (GIF, WebP, APNG) and ICO also supports animation (GIF, WebP), all frames are preserved. Converting animated JPEG to a static target (JPG, PNG) keeps only the first frame.
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.
