Image Flip & Rotate
Turn, mirror or straighten a picture — quarter turns stay pixel-for-pixel lossless.
Why A Quarter Turn Should Cost Nothing
Turning a picture by 90 degrees moves every pixel to a new position without changing a single one of them. It is a pure rearrangement, and any tool that re-samples for it is throwing away quality for no reason. The same is true of a horizontal or vertical flip.
A rotation by some other angle is a different matter entirely. Pixels no longer land on pixels, so the result has to be interpolated, and it will always be very slightly softer than the original. This tool keeps the two cases apart and tells you which one you are in, so you know whether you are paying anything for the change.
Key features
- Lossless quarter turns and flips — the pixels are moved, never recomputed.
- Fine angle adjustment — for a horizon that is two degrees out, with the result re-sampled smoothly.
- Live preview — see the result before you commit to it.
- PNG, JPEG or WebP out — with transparency flattened onto a colour you choose when saving as JPEG.
- Nothing is uploaded — the file is read into the page and stays there.
This tool runs entirely inside your browser using native Web APIs. Your files and text are never uploaded to a server, never logged and never shared with third parties.
How to use: Image Flip & Rotate
- Open your image
Drag it in or click to choose. - Turn or mirror it
The quarter-turn and flip buttons are lossless, however many times you press them. - Straighten if needed
The fine angle slider handles a crooked horizon. This one does re-sample. - Download
Pick your format. JPEG asks for a background colour if the image has transparency.

Frequently asked questions
Why does my phone show the photo the right way up but everything else shows it sideways?
The photograph carries an EXIF orientation tag that says "display this rotated", and the pixels themselves were never turned. Some software honours the tag and some ignores it. Rotating here bakes the correction into the pixels, so every program agrees from then on.
Does rotating a JPEG lose quality?
Re-encoding a JPEG always loses a little, because the compression is lossy and it is applied again. The rearrangement itself costs nothing. If quality matters, export as PNG — or accept one re-encode at high quality, which is imperceptible.
What is the difference between flipping and rotating 180 degrees?
A 180-degree rotation turns the picture upside down; a horizontal flip mirrors it left to right. On a symmetrical image they can look alike, but any text in the picture makes the difference obvious — rotation leaves it upside down and readable in a mirror, flipping leaves it the right way up and backwards.
Can I rotate several images at once?
Not in this tool — it works on one image at a time so you can see each result. For a whole folder, a desktop tool or a short script is the right instrument.
Why is a small angle blurrier than a quarter turn?
Because at 90 degrees every pixel lands exactly on another pixel, and at 2 degrees almost none of them do. Each output pixel has to be mixed from several input pixels, and mixing is what softness is. One rotation is barely visible; rotating back and forth repeatedly is not.
