Apple Touch Icon Generator
Generate 180×180, 167×167, and 152×152 Apple touch icon PNG files from one source image, then download a ZIP containing the icons and ready-to-review link markup. Cropping, padding, background color, and output are handled locally in the browser.
Local processing. The source image remains in this browser tab. Keep the editable master and validate generated assets in the platform’s official tools.

What this page produces and where it fits
Generate 180×180, 167×167, and 152×152 Apple touch icon PNG files from one source image, then download a ZIP containing the icons and ready-to-review link markup. Cropping, padding, background color, and output are handled locally in the browser. Apple touch icons represent a website saved to an Apple device Home Screen. They are separate from native iOS application icons, App Store assets, favicons, launch screens, and complete progressive web app manifests.
Icon work is a delivery system, not a single resize. A platform may use the same identity in a store, launcher, notification, settings screen, browser tab, installed web app, shortcut, or operating-system search result. Each context can apply a different mask, density, cache, compositing rule, or validation step. The generated package should therefore be treated as a tested derivative of an editable brand master.
Begin with clean source artwork. Keep the primary subject centered, remove unnecessary text, avoid hairline details, and judge the design at the smallest real display size. Do not add a platform’s outer rounded mask or system shadow to the source unless current official guidance explicitly requires that treatment. A large preview can hide problems that become obvious at 16, 32, or 48 pixels.
File dimensions alone do not prove correctness. Confirm color space, alpha behavior, file paths, MIME types, manifest or asset-catalog metadata, purpose declarations, naming, cache behavior, and actual device presentation. Preserve the source file and document which generator settings produced the reviewed release assets.

A controlled four-step icon process
- 1
Inspect the source
Choose a clear square or near-square PNG, JPG, or WebP source.
- 2
Choose settings
Select contain or cover fitting, padding, and a background color.
- 3
Generate assets
Preview the 180-pixel result and generate all three PNG sizes.
- 4
Validate delivery
Inspect the ZIP, place files at stable URLs, and add the supplied link markup to the site head.
Visual quality
Fit, detail, transparency, and recognition
Framing and padding
Fit mode changes meaning. Contain keeps the complete source and can add background around it; cover fills the square and can crop edges. Padding is useful for centered marks, but too much creates a small-looking icon. Compare masks and tiny previews before accepting a value.
Small-size detail
Raster downsizing removes detail. Thin strokes, small counters, photographic textures, and type can blur or disappear. The best small icon is often a simplified drawing rather than a mechanically reduced version of marketing artwork. Review the actual pixel output at 100% scale.
Background behavior
Transparency is not neutral. A browser, launcher, store, or operating system may composite transparent pixels against a color you did not choose. Full-bleed platform artwork should use a deliberate background where guidance expects one, while formats such as ICO may intentionally retain alpha.
Color contrast and recognition matter across light, dark, tinted, and themed environments. Test the icon near competing icons and against multiple backgrounds. Automated generation cannot determine whether a mark is distinctive, accessible, legally cleared, or consistent with current brand rules.
Important limits
What automated icon generation cannot guarantee
- The tool does not create native App Store or Xcode asset catalogs.
- Safari and device behavior can change, so test on supported physical devices.
- Fine text and edge details may become unreadable at Home Screen sizes.
- Transparent areas are flattened to the selected background to avoid unpredictable presentation.

Implementation
Configuration, caching, and release checks
Keep generated files at stable, cache-aware URLs. A manifest or HTML declaration that points to a missing file is not rescued by having the right PNG on a developer’s computer. Verify HTTP status, content type, dimensions, file bytes, and same-origin or cross-origin behavior where relevant.
Treat configuration files as reviewable code. Inspect every manifest entry, asset-catalog record, folder name, scale factor, purpose token, and filename before merging. A generated fragment intentionally avoids guessing application names, start URLs, bundle identifiers, theme colors, or project settings that belong to the real application.
Cache invalidation deserves a release check. Installed web apps, browsers, launchers, build systems, and stores can retain old icon resources. Use deliberate versioned paths or cache policy, rebuild the application, reinstall when necessary, and distinguish a stale resource from an incorrectly generated resource.
Validate both geometry and workflow. Geometry includes cropping, safe zones, centering, edge treatment, and small-size clarity. Workflow includes correct source control, repeatable settings, platform configuration, build output, deployment, and rollback. A visually attractive file can still fail because the project references a different filename.

Local processing and asset handling
The browser reads the selected source with local file APIs, draws derivatives to canvas, encodes PNG data, and assembles the requested ZIP or ICO in memory. ImageConver does not send source pixels to an icon conversion endpoint in this workflow.
Local processing reduces transfer exposure but does not make a shared device private. Browser downloads, recent-file lists, synchronized folders, backups, extensions, and operating-system previews may retain copies. Use an approved workstation for unreleased brands or confidential product artwork.
Generated object URLs are temporary and are revoked when replaced or reset. Move reviewed assets into controlled project storage, retain the editable master, and close the tab after handling sensitive materials.
Common questions
Apple Touch Icon Generator FAQ
What is the main Apple touch icon size?
A 180×180 PNG is the common modern iPhone touch icon. The ZIP also includes 167×167 and 152×152 variants for established iPad workflows.
Is an Apple touch icon the same as an iOS app icon?
No. A touch icon belongs to a website saved to the Home Screen. A native app icon is configured through Xcode and App Store tooling.
Should the artwork include rounded corners?
Do not bake in a device-specific corner mask. Supply square artwork and let the platform present it.
Can the source have transparency?
Yes, but the generator composites it onto the selected solid background because transparent presentation can vary.
Which fit mode should I use?
Contain preserves the complete artwork with padding. Cover fills the square and may crop the source edges.
Are images uploaded?
No. Decoding, resizing, PNG encoding, ZIP creation, and download occur in the active browser tab.
Do I still need a favicon?
Yes. Touch icons and favicons serve different browser and operating-system contexts, so provide both.
