How Image Converter Works

1

Drop or select images

Drag and drop one or more image files onto the upload zone, or click to browse. Any common format is accepted.

2

3

Download your images

Click Convert and download individual files or get all images bundled in a single ZIP archive.

Key Features

6 Formats Supported

Convert between PNG, JPG/JPEG, WebP, AVIF, GIF, and BMP — covering virtually every common image format.

Batch Conversion

Upload and convert dozens of images simultaneously. Each file is converted independently using the same settings.

Instant Results

Conversion uses the browser's native Canvas API — it's nearly instant even for large images.

100% Private

Your images are never uploaded. All processing happens locally in your browser using the Canvas API.

Quality Control

For lossy formats (JPG, WebP, AVIF), adjust the quality slider from 1–100 to balance file size and visual quality.

ZIP Download

Convert a batch and download all results in one click as a ZIP archive — no need to save files one by one.

Frequently Asked Questions

Q
Which image formats can I convert to?
A
You can convert to PNG, JPG (JPEG), WebP, AVIF, GIF, and BMP. You can also convert from any of these formats to any other. The tool accepts any image your browser can render.
Q
Why should I convert images to WebP?
A
WebP images are typically 25–35% smaller than equivalent JPEG files and 26% smaller than PNG files, with the same or better visual quality. Switching to WebP reduces page load times and saves bandwidth. All major browsers now support WebP.
Q
What is AVIF and should I use it?
A
AVIF (AV1 Image File Format) is the newest and most efficient image format, offering up to 50% better compression than JPEG. It is supported in Chrome, Firefox, and Safari 16+. If your audience uses modern browsers, AVIF is the best choice for photos.
Q
What does the quality slider do?
A
The quality slider controls the compression level for lossy formats (JPG, WebP, AVIF). A higher value (e.g. 85–95) produces better-looking images at larger file sizes. A lower value (e.g. 40–60) gives smaller files with more visible compression artifacts. PNG and BMP are lossless and ignore the slider.
Q
Can I convert multiple images at once?
A
Yes. You can drag and drop multiple images at once, or hold Ctrl/Cmd while selecting files. All images are converted with the same format and quality settings, then available for individual download or as a single ZIP.
Q
Are my images uploaded to a server?
A
No. The conversion uses the browser's built-in Canvas API — it runs entirely on your device. Your images are never sent over the internet, making it safe even for confidential or sensitive photos.
Q
Is there a maximum file size?
A
There is no server-side limit. The practical limit is your device's available memory. Very large images (e.g. 50+ megapixel RAW-converted TIFFs) may be slow or cause the browser to run out of memory on lower-end devices.
