How to Use the Image Converter
Converting images takes just a few seconds with no software to install. Everything runs directly in your browser - follow these simple steps to get started.
Upload Your Images
Click the upload area or drag and drop your image files directly onto it. You can select one image or many at once for batch conversion. The tool supports JPEG, PNG, WebP, GIF, BMP, and TIFF files up to 10MB each. Your images are loaded entirely in your browser - nothing is sent to any server.
Choose Your Output Format
Select the format you want to convert to by clicking one of the format buttons: JPEG, PNG, WebP, GIF, BMP, or TIFF. If you're preparing images for a website, WebP gives the best balance of quality and file size. For images that need a transparent background, choose PNG. For photographs you want to share or email, JPEG works well.
Adjust Quality and Resize (Optional)
For JPEG and WebP formats, use the quality slider to control compression. A setting of 85% is a good balance between quality and file size for most uses. For the sharpest result with no compression loss, set it to 100% or switch to PNG. You can also enter a custom width and height in pixels to resize while converting - toggle the lock icon to preserve the aspect ratio and avoid stretching.
Convert Your Images
Click the Convert Images button. A progress bar will show the conversion status for each file. The tool uses the HTML5 Canvas API to redraw and re-encode each image in your chosen format entirely within the browser - no upload, no waiting for a server response.
Preview and Download
Once conversion is complete, you'll see a side-by-side preview comparing the original and converted image, along with file size and compression information. Click Download All to save your results. Single images download directly; multiple images are packaged into a ZIP file for convenience.
Which Format Should You Choose?
Best for photographs and images with many colors. Offers excellent compression but uses lossy encoding - some quality is lost. Does not support transparent backgrounds. Ideal for sharing photos or embedding images in documents.
Best for logos, icons, screenshots, and any image that needs a transparent background. Uses lossless compression so image quality is never degraded. File sizes are larger than JPEG, but the image is pixel-perfect.
The modern web format developed by Google. Produces files 25–35% smaller than comparable JPEG or PNG images while keeping similar quality. Supports transparency and is now supported by all major browsers. The best choice for website images.
Supports simple frame-based animation and transparency, but is limited to 256 colors. Suitable for simple graphics, icons, and short animations. For static images, PNG is almost always a better choice.
An uncompressed Windows bitmap format. Produces very large files since no compression is applied, but preserves maximum image data. Mainly used in legacy Windows applications and certain print workflows where lossless raw pixel data is required.
A professional-grade format used in printing, publishing, and photography workflows. Supports lossless compression and very high color depth. TIFF files are large but retain every detail, making them ideal for archiving high-quality images.
Frequently Asked Questions
What image formats can I convert?
The converter supports six formats: JPEG, PNG, WebP, GIF, BMP, and TIFF. You can convert any of these to any other - for example, PNG to WebP, JPEG to PNG, or BMP to TIFF. All six appear as output format buttons in the Conversion Settings panel.
Is the image converter free to use?
Yes, completely free - no account, no subscription, no watermarks, and no limits on how many conversions you can do. All processing happens in your browser using open web standards, so there is no server cost to pass on to you.
Can I convert multiple images at once?
Yes. Select multiple files when browsing, or drag and drop a group of images into the upload area. All images will be converted using the same format and quality settings. When you download, multiple converted images are automatically packaged into a single ZIP file.
How do I maintain image quality during conversion?
For JPEG and WebP, set the quality slider to 90–100% to minimize compression artefacts. For truly lossless output - where no image data is lost at all - convert to PNG format. PNG compression is lossless, meaning the pixels in the output are identical to those in the input.
What is the maximum file size I can upload?
Each image can be up to 10MB. This covers most standard photos and graphics from phones and cameras. Very large raw image files may need to be resized before uploading. Since processing is entirely local, performance depends on the memory available in your browser tab.
Are my images uploaded to a server or stored anywhere?
No. Every step of the conversion happens inside your browser using the HTML5 Canvas API. Your files are never transmitted to any server, never stored in a database, and never seen by anyone but you. Closing the tab clears all data from memory immediately.
Which format should I choose for website images?
WebP is the best choice for modern websites. It achieves 25–35% smaller file sizes compared to JPEG and PNG with equivalent visual quality, which means faster page load times. It is now supported by all major browsers. Use PNG instead when you need a transparent background on a logo or icon.
Can I resize my image while converting?
Yes. Enter your target width and height in pixels in the Resize Options fields. Click the lock icon to enable aspect ratio locking - changing the width will then automatically calculate the correct height, and vice versa, so your image is never stretched or squashed.
Why is my converted PNG file larger than the original JPEG?
JPEG achieves small files by permanently discarding some image data during compression. PNG stores every pixel exactly, so its files are larger. When you convert from JPEG to PNG, the output preserves all information that was in the JPEG, resulting in a bigger file. If file size matters, stick with JPEG or convert to WebP for the best compression with good quality.
Does the converter work on phones and tablets?
Yes. The tool is fully responsive and works on iOS and Android devices. You can upload images directly from your camera roll or photo library, convert them in the browser, and download the results to your device. For best performance on mobile, keep individual images under 5MB.
