What is the fastest way to convert multiple client icon files to ICO?

Use Deliteful's batch upload. You can upload up to 50 PNG, JPG, JPEG, or WebP files in a single job and download a corresponding ICO for each one. Total batch size is limited to 2GB.

Will the ICO work for Windows installer and application manifest use?

Yes. The generated ICO contains all standard Windows icon sizes and is directly usable in application manifests, .exe resources, installer scripts, and desktop shortcuts.

My client's logo has a transparent background — will that be preserved?

Yes. Transparency is preserved where the ICO format supports it. A PNG with a transparent background will produce an ICO that renders correctly on any Windows desktop theme or wallpaper color.

Can I use this on every project without needing special software installed?

Yes. Deliteful runs entirely in the browser and processes files server-side. There is nothing to install. A free account is required and takes about 3 clicks to create with Google.

Deliver Windows ICO Files to Clients Without the Manual Export Work

Freelancers building Windows apps, desktop tools, or branded installers for clients regularly hit the same wall: the client has a logo PNG, the project needs an ICO, and converting correctly requires either specialized software or a tedious multi-step export. Deliteful converts any PNG, JPG, JPEG, or WebP into a properly structured Windows ICO file in seconds.

A professional ICO file embeds multiple sizes — typically 16, 32, 48, and 256 pixels — so Windows can render the icon correctly in every context from file explorer to high-DPI taskbar. Delivering a single-resolution PNG renamed as .ico is a common mistake that results in blurry icons and unhappy clients. Setting up a correct multi-size ICO export pipeline in GIMP or Photoshop takes 15–20 minutes per asset and requires plugins that are not installed by default.

Deliteful handles the full pipeline server-side. Upload the client artwork, download the ICO — each input image produces exactly one output file. Transparency is preserved where the ICO format supports it, so logos with transparent backgrounds carry through cleanly. For projects with multiple icon assets, batch upload supports up to 50 files per job, making it practical to process a full icon set in one pass and add it to a client deliverable folder.
