USE CASES

One Converter, Every Workflow

Wherever images end up on the web, a smaller file helps.

SEO & Page Speed

Ship lighter hero images and thumbnails so pages paint faster and search rankings benefit from a quicker load.

Social Media

Resize a batch of photos to the exact dimensions each network expects before you post them.

E-commerce

Cut down product photo weight in bulk so catalogues stay fast on slow mobile connections.

Blogs & Editorial

Compress screenshots, illustrations and article artwork while keeping graphics crisp and lossless where it matters.

Email Campaigns

Keep newsletters under size limits by shrinking the images that make up most of the message weight.

Developer Workflows

Convert a folder of assets to a modern format in one batch and pull the results down as a single ZIP.

Why Convert Images to WebP?

WebP supports both lossy and lossless compression, and it supports transparency. Depending on the original format and encoding settings, it can reduce image file sizes. Smaller images can lower bandwidth requirements, and optimized images can help improve website loading performance. WebP does not always produce a smaller file, so always compare the results shown after conversion.

Supported Image Formats

WebP

A flexible web format with lossy and lossless compression and transparency, well suited to web images.

AVIF

A modern format that can deliver strong compression and potentially smaller files. It is produced with the browser's own encoder when there is one, and otherwise with WebCodecs (AV1) plus a built-in AVIF container.

JPG and JPEG

The common choice for photographs, using lossy compression. It does not support transparency.

PNG

A lossless format that supports transparency, often used for graphics, screenshots and logos.

GIF

Encoded here with a built-in palette quantizer: the quality slider sets how many of the 256 colours are used. Transparent areas are kept.

BMP

An uncompressed 32-bit bitmap that keeps every pixel and the alpha channel. Handy for desktop software that refuses anything else.

TIFF

A print and archive format. The files are written with PackBits compression, so they stay a manageable size.

ICO

Windows icon files, written from a copy of your image that is scaled down to the 256 × 256 pixels an icon allows.

Input files are opened with the browser's own image decoder, so JPG, PNG, WebP, AVIF, GIF, BMP, SVG and ICO can all be converted.

How to Convert Images to WebP Online

  1. Upload a supported image.
  2. Choose WebP as the output format.
  3. Adjust quality and dimensions if required.
  4. Convert and download the WebP image.

Benefits of Image Compression

Frequently Asked Questions

How can I convert an image to WebP online?

Upload your image, choose WebP as the output format, adjust the quality if necessary, and click Convert Images. Download the converted file when processing is complete.

Is this image converter free?

The tool is designed to be available free of charge without requiring registration.

Can I convert JPG to WebP without losing quality?

WebP supports lossy and lossless compression. Use lossless encoding when supported and when preserving the decoded image data is important. Lossy conversion may change visual details. This tool uses your browser’s encoder in lossy mode, so a quality-setting of 100 is not guaranteed to be lossless.

Can I convert PNG to WebP while keeping transparency?

Yes. WebP supports transparency. The result depends on the source image and the selected processing settings.

Does converting images to WebP always reduce file size?

No. File-size savings depend on the original format, image content, encoding settings, and quality level.

Are my images uploaded to a server?

When browser-based processing is used, the image contents can remain on your device during conversion. Other website features and third-party scripts must be configured consistently with the site’s privacy policy.

Can I convert multiple images at once?

Yes. Select multiple supported images, configure your output settings, and convert them in one workflow. Download individual files or use the ZIP download option.

Can I resize images during conversion?

Yes. Enter the desired width and height and enable Maintain Aspect Ratio to preserve the original proportions.

Which output formats are supported?

WebP, AVIF, JPG, PNG, GIF, BMP, TIFF and ICO. WebP, JPG and PNG come from the browser's own encoder. AVIF uses the browser's encoder when it has one and WebCodecs otherwise. GIF, BMP, TIFF and ICO are written by built-in encoders and are therefore always available.

Can I convert a GIF, BMP or SVG file too?

Yes. Uploaded files are opened with the browser's own image decoder, so JPG, PNG, WebP, AVIF, GIF, BMP, SVG and ICO files can all be converted to any of the output formats.

How does the GIF conversion work?

GIF can only store up to 256 colours, so the image is reduced to a palette with a built-in quantizer. The quality slider controls how many colours are used, and transparent areas stay transparent.

Why is the TIFF preview missing?

No browser can display a TIFF file, so the result is shown as a label instead of an image. The downloaded file itself is a normal TIFF that any image editor can open.
