Will rotating a WebP lose image quality?

For an exact 90, 180, or 270 degree turn at the default Very High Image Quality setting, the visible quality is preserved — the rotation re-encodes the file, but at Very High the loss is not detectable by eye on photographic content. For lossless-mode WebPs (typically logos, UI graphics, and screenshots) the rotation can be performed without any quality loss at all because lossless WebP is bit-preserving. Custom-angle rotations (1.5 degrees, 45 degrees, etc.) always require a full pixel resample regardless of format, so a tiny encoding loss applies — generally invisible at default settings.

Will my animated WebP keep its animation after rotation?

Yes. Every frame is rotated by the same angle and the per-frame delay timings, loop count, and disposal methods are preserved, so the resulting animated WebP plays exactly like the source — just in the new orientation. This is the same behavior as competitor tools that explicitly support animated formats. If you want to convert the animated WebP to a different animated container after rotating, see WebP to GIF.

Will the transparent background survive the rotation?

Yes for 90, 180, and 270 degree rotations — every transparent and partially transparent pixel is preserved exactly. For custom-angle rotations (anything that's not a multiple of 90), the empty triangular corners created by the rotated bounding box are filled with transparency on WebPs that have an alpha channel, or with white on opaque WebPs. If you need transparent corners on an opaque WebP source, convert to a format with alpha first via WebP to PNG and rotate the PNG.

Why is my WebP saved from the web sideways even though it was a phone photo?

Phone cameras save raw sensor pixels in landscape orientation and tag the file with an EXIF Orientation value telling viewers how to display it. When the photo is uploaded to a website and re-encoded as WebP for delivery, the orientation tag is often baked into the pixels correctly — but not always. Some CDNs and image pipelines drop the orientation tag without rotating the pixels, leaving you with a sideways WebP when you "Save image as" from Chrome. Rotating the actual pixels here fixes it for any viewer.

Can I rotate a folder of WebPs all the same direction in one go?

Yes — drop in multiple WebP files and pick a rotation angle once. Every file processes in parallel with the same setting. Useful for a batch of web-saved phone portraits that all came down sideways, a folder of screen captures that exported in landscape, or a series of product mockups that need the same mirrored layout. Files download individually or as a single ZIP archive.

What's the difference between rotating and flipping a WebP?

Rotating turns the image around its center by a specified angle (90, 180, 270, or any custom value) — text inside the image stays oriented relative to the rotation. Flipping mirrors the image across an axis: a horizontal flip swaps left and right (text becomes mirror-readable / backwards), a vertical flip swaps top and bottom. A 180 degree rotation produces the same visual result as combining a horizontal and vertical flip together, but is not the same as either flip alone. For mirroring, use Flip WebP.

Will a custom-angle rotation leave colored corners on my WebP?

For WebPs that already have an alpha channel, the empty triangular corners are filled with transparency, so they blend into whatever background the image is placed against. For opaque WebPs (no alpha), the corners are filled with white by default. If you need transparent corners on an opaque source, run WebP to PNG first to add an alpha channel, rotate the PNG with Rotate PNG, and then convert back if needed.

Does this tool also work on lossless WebP from Figma or Photoshop exports?

Yes. Lossless WebP is fully supported and rotations of exactly 90, 180, or 270 degrees keep the lossless mode intact — the rotated file remains lossless and bit-equivalent in quality to the source. Mixed batches of lossy and lossless WebPs are fine; each file's mode is preserved through the rotation.

Why does my WebP file size change after rotation?

WebP compression is sensitive to byte order and pixel-row predictability, so the same pixel data can encode a few percent smaller or larger after being rotated 90 or 270 degrees (the encoder sees different patterns across rows than down columns). 180 degree rotations usually produce a near-identical file size since horizontal pixel-row patterns are similar in both directions. If you need the file smaller after rotating, drop Image Quality one notch or downscale the resolution in step 3.

Rotate WebP

Rotate WebP images by 90°, 180°, or 270°. Fix orientation of web images. Preserves transparency and quality.
