How to Flip an Image Vertically

Flipping (mirroring) turns an image left-to-right or top-to-bottom. It fixes mirrored selfies, prepares text for transfer printing and helps you inspect a composition from a fresh angle. This guide covers how to do it losslessly with the Flip Image Upside Down tool while keeping transparency intact.

The short version

Open the Flip Image Upside Down tool, add up to 30 images, set your options below, press Convert All and download — the whole job runs on your device, so it is free, private and takes seconds.

Step by step

1
Open the tool

Load the Flip Image Upside Down page. Nothing installs and nothing signs in — the editor appears immediately, ready for files.

2
Add your images

Drag files onto the drop zone, click to browse, or paste from the clipboard. You can load up to 30 at once for a batch job.

3
Confirm the axis

This tool flips vertically (top↔bottom). That is already applied — just review the preview.

4
Convert the batch

Press Convert All. Because everything runs on your device, a whole queue of photos finishes in a few seconds.

5
Download

Save each result individually, or grab the entire batch as a single ZIP. Originals are never modified.

Pro tips & common mistakes

  • Flip is lossless — there is no quality reason not to preview it.
  • Use horizontal mirror for un-mirroring selfies and for transfer-printing text.
  • Batch it: up to 30 files per run beats doing them one at a time.
  • Keep originals for anything critical — the tool never touches the source file, but always keep your master copy.

Frequently asked questions

Is this really free, with no limits?
Yes. The <a href="/flip-image-upside-down/">Flip Image Upside Down</a> tool is unlimited and free — no credits, no sign-up and no watermark on your output. There is no server doing the work, so there is nothing to meter.
Do my images get uploaded anywhere?
No. Everything is computed locally in your browser with Canvas and WebAssembly, so your files never leave your device. That is the whole privacy model of this site.
Will this reduce my image quality?
Operations run at full resolution and re-encode with quality control, so detail is preserved. PNG and WebP outputs keep transparency.
How many files can I process at once?
Up to 30 per batch — load them by dragging, clicking or pasting, run once, and download the results as a single ZIP.
Does it work on iPhone and Android?
Yes — any modern browser works: Chrome, Edge, Firefox and Safari on desktop or mobile, with no installation.
