Flip ICO

How to Flip an ICO File Online

1. Upload Your ICO File: Click "+ Add Files" or drag and drop your .ico icon. Only the first file you pick is loaded — this editor works on one image at a time, not a batch queue.
2. Pick a Flip Direction: Choose horizontal flip (mirror left-to-right, swaps the X axis) or vertical flip (mirror top-to-bottom, swaps the Y axis). Both can be combined for a 180-degree mirror.
3. Set Compression and Resolution (Optional): Under Image Compression, pick a Quality Preset (Lowest to Highest), set Target file size as a percentage, enter a Specific file size in KB/MB, or set Image Quality directly. Under Image Resolution, keep the original or rescale by percentage. Bit depth and color palette are also exposed for legacy 16- or 256-color icon work.
4. Flip and Download: Click "Flip" and download the mirrored .ico. Processing happens locally in your browser — no sign-up, no watermark.

Why Flip an ICO File?

ICO is Microsoft's icon container format, introduced with Windows 1.0 and extended for the web in March 1999 when Internet Explorer 5 added favicon support. A single .ico file packages multiple sub-images (commonly 16x16, 32x32, and 48x48; larger ICOs can include 64x64, 128x128, and 256x256), so a flip has to apply to every embedded size — not just the largest. Flipping is a lossless pixel rearrangement, so no quality is lost; that matters at 16x16 where every pixel carries weight.

• Directional icon variants — Generate a "next" arrow from a "back" arrow, a right-facing chevron from a left one, or a forward-pointing cursor from a backward one. One source design becomes a paired set without re-exporting from your design tool.
• Fix mirrored exports — Some design tools (and certain plugin pipelines that go SVG → PNG → ICO) flip the canvas during export. A horizontal flip restores the original orientation without rebuilding the source.
• Symmetrical UI pairs — Pagination controls, drawer toggles, and split-pane handles often need a left/right pair. Flip the master icon once and ship both halves at every embedded size.
• Reflection and shadow effects — Vertical flip is the foundation of a "reflected" desktop-style icon for splash screens or marketing artwork, before compositing alpha falloff in an editor.
• Localization for right-to-left layouts — Arabic, Hebrew, Persian, and Urdu interfaces typically mirror directional UI affordances. A horizontal flip retargets back/forward, undo/redo, and progress arrows for RTL builds.
• Legacy app icon refresh — Older Windows applications shipped a single 32x32 monochrome icon. Flipping and re-exporting a multi-resolution .ico modernizes the asset without redrawing it.

Horizontal vs Vertical Flip — What Each Does

If you need a non-mirroring rotation, use Rotate ICO instead — flipping reverses the chirality of asymmetric shapes (text, logos), while rotation preserves it.

Frequently Asked Questions

Does flipping reduce icon quality?

No. A flip swaps pixel positions without resampling, so there is no interpolation, blur, or color shift. A 16x16 icon stays crisp at 16x16, and a 256x256 sub-image stays at 256x256. Quality changes only if you also lower Image Quality, change the bit depth, or shrink the resolution in the same job.

Will all sub-image sizes inside the ICO get flipped?

Yes. ICO is a container — a typical favicon holds 16x16, 32x32, and 48x48 sub-images, and larger application icons can include 64x64, 128x128, and 256x256. The flip is applied to every embedded size, so the output .ico keeps the same multi-resolution structure the input had.

Will the flipped favicon still work in browsers and Windows?

Yes. The output is a standard .ico with the same sub-image sizes, color depths, and (on Vista or later) PNG-compressed payloads as the source. Chrome, Firefox, Edge, and Safari all read multi-resolution ICOs, and Windows Explorer/Taskbar read the same file for app shortcuts and pinned tiles.

Should I flip horizontally, vertically, or both?

Horizontal flip is the right answer for almost every directional UI case (arrows, back/forward, drawer handles, RTL mirroring). Vertical flip is rarer and mostly used for reflection effects, upside-down map markers, or "drop" indicators. Selecting both flips is equivalent to a 180-degree rotation.

Does the tool preserve transparency and the alpha channel?

Yes. ICO has supported a 1-bit AND mask since Windows 1.0 and full 8-bit alpha since Windows XP (32-bit color depth). The flip operation moves the alpha channel along with the RGB pixels, so anti-aliased edges, soft drop shadows, and semi-transparent fills all survive intact.

Why does my flipped icon look slightly different at 16x16?

At 16x16, anti-aliased edges that were tuned for one direction (say, the right side of a chevron) end up on the opposite side after a flip. The pixel values are unchanged, but the perceptual weight shifts because human eyes are sensitive to which side of a glyph is "heavy." If the result reads worse, redraw the 16x16 sub-image in a pixel editor — automatic flipping cannot recover hand-pixel-hinting that was directional.

Can I flip an ICO that contains text or letterforms?

You can, but text reverses with the flip — a horizontal flip turns "F" into a mirrored F, which is rarely desired. For lettered icons, flip in your source tool, re-typeset the glyph, and re-export. For glyph-free directional icons (arrows, chevrons, hands), a flip works as expected.

How is this different from rotating 180 degrees?

A 180-degree rotation is identical to a horizontal-and-vertical flip combined — every pixel moves to the diagonally opposite position. A single horizontal flip is not a rotation; it inverts left/right only. Use Rotate ICO for 90- or 270-degree turns where mirroring would be wrong (asymmetric logos, text).

Can I batch-flip multiple ICO files?

Not on this page — the editor loads one file at a time. Flip it, save, then + Start New for the next icon, picking the same direction each time. Each file's full multi-resolution structure (16, 32, 48, and any larger sub-images) is preserved.

What if I need other ICO operations?

Pair flipping with Compress ICO to shrink large 256x256 PNG-compressed icons, or with Convert PNG to ICO and Convert ICO to PNG when moving assets between web and Windows pipelines. For broader image-flip workflows, see Flip PNG or Flip Image.
