Why flipping images matters
Flipping is one of the simplest and most common image edits — yet most people reach for heavyweight software just to mirror a photo. Whether you are fixing a mirrored selfie, correcting the orientation of a scanned document, or creating a reflection effect for a design layout, this tool does it in one click with zero learning curve.
As a concrete example: a 4032 × 3024 selfie from an iPhone (roughly 2.8 MB JPEG) that was captured mirrored can be flipped horizontally back to normal. The output is a 4032 × 3024 JPEG at the same quality — the pixels are simply rearranged. No recompression, no quality loss, no dimension change. The entire operation completes in under 200 milliseconds on a desktop browser.
How the Canvas API flips work
The tool uses the browser's native Canvas API to mirror pixel data. For a horizontal flip, the canvas transform is set to ctx.scale(-1, 1), which mirrors the X axis. For a vertical flip, ctx.scale(1, -1) mirrors the Y axis. When both are applied together, the result is equivalent to a 180° rotation — every pixel maps to its opposite corner. Because the operation only rearranges existing pixels without interpolation or blending, the output is mathematically lossless aside from the canvas re-encoding step.
Flip vs rotate — know the difference
A horizontal flip mirrors the image left-to-right, as if you held it up to a mirror. A vertical flip mirrors it top-to-bottom, turning it upside-down. A rotation turns the image around its center by a given angle. Flipping a portrait photo horizontally is how you correct a mirrored selfie; rotating it 180° is how you fix a photo that was taken upside-down. These are distinct transforms, and this tool focuses on the former. For rotation, we have a dedicated Rotate Image tool.
Why no-upload matters
Photos are among the most personal files on any device. They can contain faces, home interiors, ID documents, private screenshots of messages, or medical images. Upload-based flip tools send your original file to a remote server for processing — and you have no way to verify it was deleted afterward. This tool runs entirely inside your browser's JavaScript runtime. The canvas operations execute locally, the output Blob is created in-memory, and the download streams directly from your tab to your filesystem. Zero bytes of your image leave your device at any point.

Frequently asked questions
Is my image uploaded to a server?+
No. The entire flip runs in your browser using the Canvas API. Your image never leaves your device, never touches our servers, and is never logged or stored anywhere.
What image formats are supported?+
JPG, PNG, WebP, GIF, BMP, and AVIF. The tool auto-detects the format — just drop any image file. The output preserves your original format.
What is the maximum file size?+
You can flip images up to 50 MB. Files over 25 MB will show a warning since processing may be slower on mobile devices due to memory limits per browser tab.
Will this work on mobile?+
Yes, on modern mobile browsers (Chrome, Safari, Firefox). The flip is instantaneous for most images. Very large images (>25 MB) may take a moment on older phones due to canvas rendering.
What exactly does "flip" mean vs "rotate"?+
Flipping creates a mirror image — horizontally (left ↔ right), vertically (top ↔ bottom), or both. Rotation turns the image by an angle (e.g. 90°, 180°). A horizontal flip is what you see in a mirror; a vertical flip turns the image upside-down. If you need rotation, use our Rotate Image tool.
Can I apply both horizontal and vertical flips at once?+
Yes. Click both buttons and the image will be flipped in both directions. The live preview updates instantly so you can see the result. Clicking one button a second time toggles the flip off — both directions are cumulative.
Does flipping reduce image quality?+
No — the effect is lossless. The pixel data is simply repositioned within the canvas at the same resolution. The output file is re-encoded from the canvas, so the quality stays identical to the original.
Why would I need to flip an image?+
Common use cases: fixing a selfie that was captured mirrored, correcting a scanned document fed upside-down, preparing assets for print layouts that require mirrored duplicates, or simply creating a reflection effect for design work.
