3Apply the flip, then check any text, logos or numbers in the preview, because those mirror along with everything else.

Flip JPEG FAQ
Does the source format matter when flipping?
+
It does. JPEG is the same codec as JPG under a longer extension — identical DCT pipeline, identical quantisation tables, nothing about the pixels changes with the filename. That is what decides whether the mirror can be done by rewriting the file or requires decoding it first.
Anything specific to JPEG to be aware of?
+
Yes — the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes. Worth a moment before you flip something you cannot easily recreate.
How does Flip JPEG mirror the file?
+
Concretely, a horizontal or vertical mirror is a lossless DCT transform, so the file is rewritten without decoding and re-encoding the image at all — the output is pixel-identical to a mirrored original. You choose the axis — horizontal produces a mirror image, vertical produces an upside-down reflection — and the whole file is transformed on it.
What is the difference between flipping and rotating?
+
A flip reverses the content across an axis and produces a mirror image; a rotation turns it without reversing anything. Text is the giveaway: it reads backwards after a flip and stays readable after a rotation.
What happens to EXIF and colour profile data?
+
It depends on the tool. Compression strips EXIF and the embedded colour profile to save space, while edits such as resizing or rotating can keep them. There is no setting on this page to choose, so check the file with a metadata viewer before publishing it if location data matters.
What can I upload to Flip JPEG?
+
Anything in the lossy raster family — JPG, JPEG, JFIF and WebP — plus the lossless formats (PNG, BMP, TIFF) if you want to mix them in one batch. The format is read from the file header, not the extension, so a photo saved with the wrong suffix still goes through.
Is there a file size limit on Flip JPEG?
+
Yes: free accounts process images up to 5 MB each, which covers essentially every camera JPG and phone photo; the work is done by libjpeg-turbo and libwebp, the same libraries a desktop editor links against. Larger files are the one thing the free tier will stop you on, and the limit is per file rather than per batch.
Why would a modern-format site run Flip JPEG?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Flip JPEG is on the same upload and the same account so those questions get answered in one place.
Once Flip JPEG has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
