Flip WebP images horizontally or vertically, with transparency kept. Adjust quality and download instantly.
WebP is the format Chrome, Firefox, Edge, Opera, and Safari 16+ (with partial support since Safari 14 / iOS 14) all decode natively, so site owners ship WebP rather than JPEG or PNG to cut page weight. That makes "flip the WebP I already exported" a more common task than "convert it first": flipping the WebP directly avoids a separate round-trip through JPEG/PNG. One caveat: this editor always writes WebP lossy, so for a lossless WebP (screenshots, line art) pick PNG in "Save as".
| Flip Direction | What It Does | When To Use It | Common Alternative |
|---|---|---|---|
| Horizontal (mirror) | Swaps left ↔ right pixels along the vertical axis | Un-mirror selfies, reverse subject gaze, fix backwards text, build paired-arrow sprites | 180° rotate (only matches if image is also symmetric top-bottom) |
| Vertical | Swaps top ↔ bottom pixels along the horizontal axis | Reflection effects, upside-down scans, mirrored signage shots | 180° rotate then horizontal flip — same result, two steps |
| Both (H + V) | Equivalent to a 180° rotation | Quick way to invert orientation if the tool only exposes flip toggles | Rotate WebP at 180° |
A flip is not the same as a rotation — rotation preserves text legibility (text rotated 180° reads upside-down but in correct order); a horizontal flip reverses the reading order, so any text in the image becomes mirror writing.
| Setting | What it does | When to change it |
|---|---|---|
| "Horizontal" / "Vertical" | Mirrors the photo left-right or top-bottom; click again to undo | Selfie text, a logo facing the wrong way, an upside-down scan |
| "Save as" | "Same as original", or JPG, PNG, WebP, GIF, BMP, TIFF, ICO, AVIF, PSD, PPM | The destination needs another format |
| "Quality" (40–100, starts at 85) | Re-encode quality for JPG, WebP and AVIF output | Lower for smaller files, higher before more editing |
| Resize (same session) | Changes the pixel size along with the flip | Downscale for the web in one pass |
The editor has no DPI, bit-depth, compression-type or file-size-target setting. To hit a byte budget, run the result through Compress WebP.
A flip itself is a lossless pixel-coordinate transform — the pixels are simply written in mirrored order. WebP output from this editor is always lossy, though, even at "Quality" 100 (there is no lossless WebP mode), so the re-encode after the flip introduces a small generation loss (typically hard to see on photographs at the default "Quality" of 85). For screenshots, line art, and assets you'll edit again later, save as PNG instead.
Yes. WebP supports an 8-bit alpha channel in both lossy and lossless modes, and the flip operation mirrors the alpha values together with the RGB values. Stickers, cut-out PNG-style WebP assets, and UI icons keep their transparent backgrounds.
No. The editor on this page works on the first frame and says so when an animated WebP opens: an animated WebP you flip here is saved as a still image of that frame, and the other frames are not kept. Downloading the file without an edit gives back the original, animation intact.
iOS shows you a mirrored preview while you frame the shot (so the image moves the way a mirror does), but by default it saves the un-mirrored "true" capture — which is what someone facing you would actually see. If text or a logo behind you reads backwards, a horizontal flip fixes it. Apple added an opt-in Settings → Camera → Mirror Front Camera toggle to save the mirrored version directly, but it's off by default and only applies to new shots.
No. A 180° rotation turns the image upside-down and swaps left/right; a horizontal flip only swaps left/right. Visually it's only the same when the image is already symmetric top-to-bottom. If you want a true rotation, use the Rotate tab (or Rotate WebP) and turn it in 90° steps with "90° left" or "90° right".
Yes. Click "Horizontal" or "Vertical" in Flip, then open Resize and set a "Width", "Height" or "Size preset" (percent of original, a target height such as 720p or 1080p, or a platform size). Both edits are applied in a single encode when you download, which is cleaner than flipping, downloading and re-uploading to resize.
The WebP container itself caps at 16,383 × 16,383 pixels (per the WebP spec). Files within that limit flip without issue. If you need to convert beyond that ceiling, switch the output to PNG or TIFF, which have far higher dimension caps.
No. A WebP saved here carries no EXIF block, so camera, lens, and GPS tags are not kept (the editor keeps EXIF only when a JPG or HEIC photo is saved as JPG). The flip is baked into the pixels, so there is no Orientation flag left to misread — which avoids the long-standing "looks right in Photos but mirrored on the web" bug caused by viewers ignoring the Orientation flag.
Yes — the output is still a valid WebP file. Every modern browser (Chrome, Firefox, Edge, Opera, Safari 16+ — and partially since Safari 14 / macOS Big Sur) renders it. For older Safari (≤13) or legacy contexts, convert to JPG or PNG after flipping.
