Images in one batch

Batch, resize, quality, transparency, and ZIP controls run locally in your browser.

Quality, dimensions, and alpha fill

Tune JPG and WebP output, keep aspect ratio, and choose how transparent pixels become JPG.

From source file to useful output

One direct workflow for a single image or a complete folder.

Add the source images

Drag files onto the tool, browse your device, or paste an image from the clipboard.

Set the output once

Choose JPG, PNG, or WebP, then open settings for quality, size, or a background color.

Download files or one ZIP

Review each result and save it alone or package the finished batch.

Ten source formats, three practical outputs

Use JPG for compatibility, PNG for lossless pixels, and WebP for compact web delivery.

Modern and phone photos

AVIF, HEIC, and WebP

AVIFA modern image format built for strong compression, HDR color, and optional transparency.
HEICThe compact photo container commonly produced by iPhone and iPad cameras.
WEBPA modern web format that balances compact files, quality, and transparency.

Standard images

JPG, PNG, and JFIF

JPGThe most widely accepted photo format, with adjustable lossy compression.
PNGA lossless format that keeps sharp edges and full alpha transparency.
JFIFA common JPEG interchange wrapper that some upload forms and desktop tools expose with a .jfif extension.

Legacy and animated

GIF and BMP

GIFAn indexed-color format best known for simple looping animations and compact web graphics.
BMPA legacy raster format that usually stores pixels with little or no compression.

Vector and print

SVG and TIFF

SVGAn XML-based vector format that stays sharp at any size and can include text, shapes, and gradients.
TIFFA flexible raster container used for scans, print work, archives, and high-bit-depth images.

Dedicated image format converters

Questions about local conversion

Are my images uploaded to a server?

No. Decoding, resizing, and encoding happen in your browser. Selected files stay in browser memory until you clear the queue, refresh, or close the tab.

Can I convert several images at once?

Yes. Add up to 100 images, apply one set of output settings, and download results individually or together in a ZIP.

Which source formats are supported?

The converter accepts AVIF, HEIC, HEIF, JPG, JPEG, PNG, WebP, GIF, BMP, SVG, TIFF, TIF, and JFIF. Output is available as JPG, PNG, or WebP.

What happens to EXIF and GPS metadata?

Converted files are rendered through a fresh canvas, so EXIF, GPS, camera, profile, and comment metadata is not copied.

How are animation and multi-page files handled?

GIF, animated WebP, and animated AVIF export the first frame. Multi-page TIFF and multi-image HEIC export the first readable image.

Does the converter work on phones?

It works in current mobile browsers. Smaller batches are more reliable on older phones because large images use significant memory.
