Image Format Converter

Rotate or mirror a picture

Use the image rotator and flipper for quarter turns, custom angles, horizontal or vertical flips, live preview and batch export.

Choose JPG, PNG or WebP

JPG is a lossy format suited to many photographs, but it cannot keep transparency. PNG uses lossless pixel encoding and can keep transparent areas; photographs can become much larger as PNG. WebP supports transparency and often provides useful web delivery sizes, but check the format requirements of the service receiving your file.

A format change does not restore detail lost earlier. Turning a JPG into PNG prevents new lossy PNG encoding; it cannot recover the JPG's discarded detail. This converter's WebP output uses the browser's quality-based encoder, not a guaranteed lossless mode.

Handle transparent edges deliberately

To add your name or a logo to a prepared picture, use the image watermark tool with live positioning and batch export.

For PNG and WebP, choose Preserve transparency or fill it with a solid colour. JPG always uses the chosen background colour, initially white. Partly transparent edges blend with that background, so inspect logos and cutouts against the colour you plan to use.

This is not a background remover: a white wall or any other opaque part of a picture remains. To change the composition first, use the image cropper.

Compare dimensions and file size separately

The output keeps the browser-decoded image dimensions, including supported camera orientation. Each result reports input and output formats, dimensions and encoded bytes. A format conversion can increase file size even when the picture looks the same.

All files in a run use the same settings and start from their originals. Changing settings removes earlier conversion downloads so you can prepare fresh results. Cancel keeps completed results and waits for the current browser operation to finish. ZIP includes successful, available results only, with a unique batch number in each filename.

Local processing and practical limits

Selected image contents are processed here in this browser without uploading them for conversion. The website still loads scripts and shared services. Reloading or clearing loses the current batch; it does not delete originals or files you have downloaded.

Limits: 20 files, 25 MiB each and 200 MiB combined input; 40 megapixels and 16,000 pixels per side for source headers; output keeps dimensions with a 12,000-pixel side limit and a 200 MiB cap on available results. Actual device memory may require smaller batches. Animated PNG/WebP, GIF, SVG, HEIC and AVIF are not supported inputs.

Re-encoding may change colour profiles, metadata and appearance. This tool does not promise complete metadata removal. Keep originals and check the result. Read the Privacy Policy or report a problem with the browser, input type and output settings.
