Convert Images Between Any Format

Image Format Converter is a browser-based tool that converts your images between popular formats including JPEG, PNG, WebP, GIF, BMP, AVIF, SVG, and HEIC. Whether you need to convert a PNG screenshot to JPEG for smaller file size, transform Apple HEIC photos to a universal format, or modernize images to WebP for the web, this tool handles it instantly.

Complete Privacy: All processing happens entirely in your browser — your images are never uploaded to any server, ensuring complete privacy and instant results.

Supported Formats

JPEG

Most widely supported lossy format. Ideal for photographs with adjustable quality (10-100).

PNG

Lossless format with transparency support. Best for graphics, icons, and screenshots.

WebP

Modern format by Google with superior compression. Supports both lossy and transparency with adjustable quality.

GIF

Limited to 256 colors. Best for simple graphics. Animated GIFs are converted as a single frame.

BMP

Uncompressed bitmap format. Large file sizes but no quality loss.

AVIF

Next-generation format with excellent compression, even better than WebP. Adjustable quality.

SVG

Vector format (input only). Converted to raster formats at the original dimensions.

HEIC/HEIF

Apple's default photo format (input only). Requires the heic2any decoder library.

How to Convert Images

Choose the Target Format

Select your desired output format (JPG, PNG, WebP, GIF, BMP, or AVIF) from the format buttons. Or use a dedicated sub-app like "PNG to JPG" for a specific conversion.

Upload Your Images

Drag and drop files into the upload zone, click to browse, or paste from your clipboard (Ctrl+V). You can upload up to 20 images at once.

Adjust Quality

For JPEG, WebP, and AVIF, use the quality slider (10-100) to balance file size and quality. PNG, GIF, and BMP are converted without quality loss.

Automatic Conversion

Conversion starts instantly when you upload. Changing the format or quality automatically reconverts all images.

Download Results

Download individual converted images or use "Download All (ZIP)" to get everything in a single archive.

Frequently Asked Questions

What quality setting should I use?

A quality of 85 is recommended for most use cases, providing a good balance between file size and visual quality.

Web images (60-75): When file size matters for faster loading
General use (85): Optimal balance for everyday conversions
Archival/High-quality (90-100): For professional or preservation purposes

Why does my converted file have a white background?

JPEG and BMP formats do not support transparency. When converting from a format with transparent areas (like PNG), the tool fills those areas with a white background to prevent them from appearing black.

Tip: To preserve transparency, convert to PNG, WebP, GIF, or AVIF instead.

Can I convert HEIC photos from my iPhone?

Yes. The tool supports HEIC/HEIF format conversion using the heic2any library, which is loaded on-demand when you upload a HEIC file. You can convert HEIC to JPEG, PNG, WebP, or any other supported format.

Can I convert SVG files?

Yes, SVG files can be converted to any raster format (JPEG, PNG, WebP, etc.). The tool renders the SVG at its original dimensions (or 800x600 if no dimensions are specified) and then converts the rasterized result.

Why can't I convert to SVG or HEIC?

Converting raster images to SVG would require vector tracing, which produces poor results for photographs. HEIC encoding is not natively supported by web browsers. Both SVG and HEIC are supported as input formats only.

Are my images uploaded to a server?

No. All conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device. This ensures complete privacy and also means the tool works offline after the page loads.

How many images can I convert at once?

You can convert up to 20 images in a single batch. If you need to convert more, download the current batch and clear the list to start a new one.

Why is my converted file larger than the original?

This can happen when converting from a highly compressed format to a less compressed one (e.g., JPEG to PNG), or when using very high quality settings. PNG and BMP outputs are typically larger than JPEG or WebP equivalents because they use lossless compression or no compression at all.

Note: For smaller file sizes, use JPEG (quality 60-85), WebP, or AVIF formats.

What is the difference between AVIF and WebP?

Both are modern formats with excellent compression. Here's how they compare:

Feature	AVIF	WebP
Compression	20% better	Excellent
Browser Support	Limited	Widely supported
Transparency	Yes	Yes
Quality Control	Adjustable	Adjustable

Recommendation: Use WebP for maximum compatibility, or AVIF when targeting modern browsers and need the best compression.
