Convert JPG, PNG, WebP and AVIF Images

Different projects require different image formats. A website may benefit from WebP images, a graphic design project may need transparent PNG files, and everyday photos are often stored as JPG.

FastTL Image Format Converter Pro brings common image conversion options together in one place.

• JPG to WebP: Convert supported JPG images into WebP for modern websites.
• PNG to JPG: Convert PNG images to JPG when transparency is not required.
• JPG to PNG: Create PNG versions of supported JPG images.
• WebP to PNG: Convert supported WebP images into PNG.
• PNG to WebP: Convert PNG images to WebP where browser support allows.
• AVIF conversion: Work with AVIF input or output when your browser supports the required format.

Actual conversion options depend on your browser and its image encoding support. Not every format is available in every browser.

Why Use FastTL Image Format Converter?

Batch Image Conversion

Working with multiple images? Select several files and process them in one session instead of converting each image separately. You can download individual results and, when the ZIP feature is available, package multiple converted images together.

Resize Images to Your Needs

Adjust image dimensions before downloading your converted files. Resizing can help prepare images for websites, online shops, presentations, and social media.

Always check the final dimensions before using an image in a project with specific size requirements.

Adjust Image Quality

For supported lossy formats, quality settings can help you balance visual appearance and file size. A higher quality setting may preserve more visual detail, while a lower setting may produce a smaller file.

The final file size depends on the original image, selected format, dimensions, and browser encoder. Conversion does not guarantee a smaller file.

Preview Before Downloading

Preview your source image and converted result before saving the output. This makes it easier to check image appearance and confirm that the conversion produced the expected result.

Download Your Converted Images

Download converted images individually. If batch ZIP creation is enabled and supported, you can also download multiple results in one archive.

A Convenient Browser-Based Workflow

FastTL’s image conversion process runs in your browser. The converter is designed to process selected images locally instead of requiring you to upload them to the FastTL server for conversion.

Your browser still needs sufficient memory and processing power, especially when handling large images or multiple files.

How to Convert Images Online

Converting an image takes just a few steps:

1. Open the Image Format Converter Pro above.
2. Select or drag and drop the images you want to convert.
3. Choose a supported output format, such as JPG, PNG, WebP, or AVIF.
4. Adjust quality and image dimensions if needed.
5. Start the conversion and review the result.
6. Download your converted image or use the available batch download option.

For best results, test a single image first when working with large files or an unfamiliar format.

Which Image Format Should You Choose?

JPG / JPEG

JPG is widely supported and commonly used for photographs. It is a practical option when broad compatibility matters and transparency is not needed.

PNG

PNG is useful for graphics, screenshots, logos, and images that require transparency. PNG files can be larger than comparable lossy images, depending on the content.

WebP

WebP supports lossy and lossless image compression, as well as transparency. It is a useful choice for many modern websites, although you should consider your site’s compatibility requirements.

AVIF

AVIF can deliver efficient compression and supports features such as transparency and high dynamic range in compatible workflows. Encoding and decoding support varies across browsers and devices.

Tip: Choose a format based on image quality, file size, transparency needs, and where the image will be used.

Frequently Asked Questions

Is FastTL Image Format Converter free?

The tool is designed to provide convenient image conversion through FastTL. Check the tool interface for the options currently available.

Can I convert JPG to WebP online?

Yes. Select JPG images, choose WebP as the output format when it is supported by your browser, and start the conversion.

Can I convert PNG to JPG?

Yes, when your browser supports the required conversion. Keep in mind that JPG does not support transparency, so transparent areas may be filled with a background color.

Can I convert WebP to PNG?

Yes, if your browser can decode the source WebP image and supports PNG output. PNG is useful when you need a format that supports transparency.

Does the converter support AVIF?

AVIF support depends on the browser’s ability to decode AVIF input and encode AVIF output. If a required operation is unsupported, choose another format or use a compatible browser.

Can I convert multiple images at once?

The converter includes batch-processing functionality. The number and size of images you can process at once depend on available device memory and browser performance.

Are my images uploaded to FastTL?

The browser-based conversion workflow is designed to process images locally without uploading them to the FastTL server for conversion. Normal website requests and third-party resources used by the page may still connect to their respective servers.

Does converting an image always reduce its size?

No. Some conversions produce smaller files, while others may increase file size. The result depends on the source image, output format, quality settings, and dimensions.

Will converting an image improve its quality?

Changing the format does not restore missing details or automatically improve image quality. When converting to a lossy format, some visual information may be lost.
