The converter runs locally in your browser. There is no account, server upload, or waiting for a remote job to finish.

  1. 01
    Choose your images

    Add one file or a batch of JPEG, PNG, WebP, or AVIF images up to 30 MB each.

    Download the result

    Save images individually or download the completed batch together as a ZIP file.

Use AVIF when a smaller modern image matters.

AVIF supports transparency and can create compact files from detailed PNG images. It is especially useful when a PNG contains photographic detail, gradients, or many colors rather than simple flat artwork.

AVIF takes longer to encode than WebP, so large batches may need a little patience. Start around 90% quality, inspect the downloaded result, and lower the setting when reducing file size is more important than preserving very fine detail.

Local by design

Your files remain on your device. The browser handles decoding, resizing, and encoding.

Batch friendly

Process several images with the same settings and collect the finished files in one ZIP.

Useful controls

Balance quality and file size, resize proportionally, or use lossless WebP for pixel-perfect output.

Which format should you choose?

For most websites, WebP at 90% is a dependable default. Try AVIF when the smallest possible file matters and you can spend a little longer encoding it.

WebP
Fast to create, broadly useful, and a good choice for everyday website images.
AVIF
Often produces smaller files, especially for photographs, but takes longer to encode.
Quality
Start at 90%. Lower it when file size matters more; raise it for detailed artwork or text.

Your images stay on your device.

The converter has no image upload endpoint. Your browser decodes, resizes and encodes each file locally. Standard host request logs never contain your image files or conversion settings.

Image conversion questions

Practical answers about quality, privacy, supported files, and browser-based conversion.

Do my images leave my device?

No. The image data is decoded and converted inside your browser. The website has no image upload endpoint.

Which image formats can I convert?

You can add JPEG, PNG, WebP, and AVIF files and export them as WebP or AVIF. Each source image can be up to 30 MB.

Should I choose WebP or AVIF?

WebP is a dependable default with fast encoding and broad support. AVIF often creates smaller files, especially for photographs, but takes longer to encode.

What quality setting should I use?

Start at 90% for general website use. Lower it when file size matters more, or raise it for screenshots, text, and detailed artwork.

Will transparent backgrounds be preserved?

Yes. WebP and AVIF both support transparency, so transparent areas in compatible source files can remain transparent.

What happens to EXIF and location metadata?

The converter applies the source orientation and creates a new output without copying EXIF, location data, comments, or other source metadata.
