Convert, Optimize, and Resize Your Images
A powerful tool for converting images between formats with advanced options for quality control, resizing, and optimization. Supports PNG, JPEG, WebP, BMP, and AVIF formats.
The Image Format Converter tool allows you to convert images between different formats while maintaining control over quality, dimensions, and file size. Whether you need to optimize images for web use or prepare them for specific applications, this tool has you covered.
Tip: The tool supports images up to 10MB in size. For best results, use high-quality source images.
The tool supports multiple methods for uploading your images, making it easy to get started regardless of your preference.
Simply drag your image file from your computer and drop it onto the upload area. The dashed border will highlight when you're dragging a valid file.
Click anywhere on the upload area to open your file browser and select an image manually.
Note: Once you upload an image, the tool will automatically suggest a different output format (if you uploaded a PNG, for example, it won't suggest PNG as the output format).
Choose from several output formats, each with different compression methods and use cases.
Lossless compression with transparency support. Ideal for graphics, logos, screenshots, and images requiring sharp edges or transparent backgrounds.
Lossy compression with smaller file sizes. Best for photographs, complex images, and situations where file size is more important than perfect quality.
Modern format supporting both lossy and lossless compression. Provides excellent quality at smaller file sizes. Ideal for web use and modern applications.
Uncompressed format with no compression. Produces large files but maintains exact pixel data. Best for image editing, archival, or when lossless quality is critical.
Ultra-modern format with the best compression available. Supports both lossy and lossless compression. Best for high-quality web images where browser support is available.
For formats that support lossy compression (JPEG, WebP, AVIF), you can adjust the quality slider to balance between file size and image quality.
The quality slider ranges from 10% to 100%, allowing fine-grained control over the output:
Note: PNG and BMP formats use lossless compression, so the quality slider has no effect on these formats.
Lower quality settings produce smaller files, ideal for web optimization and bandwidth-constrained scenarios.
Higher quality settings preserve more detail, suitable for high-resolution displays and print materials.
The tool includes powerful resizing capabilities with aspect ratio preservation to help you prepare images for specific use cases.
When enabled, changing one dimension automatically adjusts the other to preserve the original proportions. This prevents distortion and keeps your images looking natural.
Disable aspect ratio to set exact width and height values independently. Useful for creating images with specific dimensions for layouts or thumbnails.
Tip: Enter only one dimension (width OR height) when maintaining aspect ratio, and the other will be calculated automatically based on the original image dimensions.
Control whether EXIF data and other metadata are preserved during conversion.
When enabled, the converted image will retain EXIF data such as:
Keep metadata for personal photo collections, archival purposes, or when you need to preserve copyright and ownership information.
Remove metadata for privacy (hiding location data), when sharing images publicly, or to reduce file size.
Note: Metadata preservation is not supported for all format combinations. Some output formats may not preserve all types of metadata regardless of this setting.
The tool provides a comprehensive preview section that shows both the original and converted images side by side for easy comparison.
Zoom in up to 300% or zoom out to 50% using the zoom buttons in the preview corners. Double-click to reset zoom.
Click and drag to pan around zoomed images. Works independently for original and converted previews.
View file sizes for both original and converted images, plus see the compression ratio percentage.
Each preview shows the image format and file size, making it easy to identify and compare results.
After conversion, you'll see a badge showing how much smaller or larger the converted file is compared to the original:
Once your image is converted, you can download it with a single click.
Download [Format] ([Size])
Click to save the converted image to your computer
Downloaded files are automatically named "converted.[ext]" where [ext] is the output format extension (e.g., converted.webp, converted.jpg).
Tip: Rename the file after downloading if you need to preserve a specific naming convention.
Use this comparison table to choose the best format for your needs.
| Format | Compression | Transparency | Best For |
|---|---|---|---|
| PNG | Lossless | Yes | Graphics, logos, screenshots |
| JPEG | Lossy | No | Photographs, complex images |
| WebP | Both | Yes | Web use, modern applications |
| BMP | None | Yes | Editing, archival |
| AVIF | Both | Yes | High quality web images |
Convert images to WebP or JPEG with reduced quality to create smaller, faster-loading web pages. Use 70-85% quality for a good balance.
Resize and convert images to meet platform requirements. Most social media platforms work best with JPEG or PNG formats.
Convert logos to PNG for transparency support, or SVG for scalability. Keep lossless compression for sharp edges.
Use PNG or high-quality JPEG to preserve photo detail. Keep metadata if you need to track camera settings.
Compress images to JPEG to reduce file size for email. Aim for under 1MB total for attachments when possible.
Generate multiple sizes from source images. Use WebP for Android and consider HEIC for iOS where supported.
