What Rotate & Flip does
Rotate & Flip fixes photos that are sideways, upside down or mirrored, and can also straighten a crooked horizon with a fine-angle control. It works on batches, so a phone album full of inconsistently oriented shots can be corrected in one pass.
Quick buttons rotate by 90° left or right, 180°, or flip horizontally and vertically. For straightening, the fine angle slider covers ±180° with an optional 15° snap, and a straighten grid helps line up horizontal and vertical features.
Rotating at an angle leaves empty corners. You choose what happens to them: keep transparency (PNG/WebP), fill with a colour, or let the tool auto-crop to the largest centred rectangle that contains only real pixels.
How to use Rotate & Flip
- Drop one or more images onto the page, or click the dropzone to browse.
- Use the quick controls: ⟲ 90° left, ⟳ 90° right, 180°, ⇋ Flip H or ⇅ Flip V.
- For straightening, drag the fine angle slider (or enable Snap 15° and use the straighten grid).
- Choose what happens to empty corners: Transparent, Fill colour or Auto-crop to largest rectangle.
- Pick the output format and quality, and check the live preview of the resulting dimensions.
- Click Rotate & download all, retry any failures, and download files individually or as a ZIP. Undo, redo and reset are available while editing.
Features
- Batch rotation of 90° left/right, 180°, horizontal flip and vertical flip.
- Fine-angle straightening from ±180° with optional 15° snap and a straighten grid.
- Three corner treatments for angled rotations: transparent, solid fill or automatic crop to the largest rectangle.
- Live preview showing the exact output dimensions before export.
- Worker-based processing with undo, redo and reset, plus per-file retry and ZIP export.
- Output as the original format, JPEG, PNG or WebP with a quality setting; EXIF orientation is applied at decode and metadata is not carried over.
Tips and common mistakes
- Straighten first, then use the quick 90° buttons if needed — that order keeps the grid useful for judging the angle.
- Use auto-crop for photos where the edges matter less than a clean rectangular result.
- For scanned documents, a 0.5–2° straighten with edge filling often makes text alignment look noticeably tidier.
Frequently asked questions
Why do my rotated photos have white corners?
JPEG cannot store transparency, so any empty area left by an angled rotation becomes white or the fill colour you selected. Choose Auto-crop to trim those corners away, or export PNG or WebP to keep them transparent.
Does auto-crop change the dimensions?
Yes — auto-crop finds the largest centred rectangle that contains only real image data, so the output is smaller than the original. That is the trade-off for a clean, corner-free result at non-zero angles.
What is the difference between Rotate left and Rotate right?
Both rotate by 90°, in opposite directions. If a portrait photo appears sideways, one of the two will correct it; there is no wrong choice because undo is always available.
My photo looked correct before, but now it is sideways. Why?
Some cameras store orientation as metadata rather than rotating the pixels. This tool applies the embedded orientation when decoding and does not write it back, so the visual result is what you see in the preview — orientation metadata will not re-rotate it later.
Can I fix a crooked scan?
Yes. Use the straighten grid to align a known vertical or horizontal line, adjust the fine angle until the line matches the grid, then choose Auto-crop to remove the resulting corners.
