Image Compressor

How to Compress Images Online for Free

This free image compressor reduces the file size of your photos and graphics directly in your browser. Nothing is uploaded to a server, there is no sign-up, and no watermark is added to your result.

Steps

Choose an image from your device.
Pick an output format: same as original, JPG or WebP.
Lower the quality slider to shrink the file. Values between 60 and 80 usually look nearly identical.
Optionally set a maximum width in pixels to scale large images down.
Click Convert, check the new size, and download the result.

Compress PNG Without Losing Background Transparency Free Online

Transparent backgrounds are kept when the output is PNG or WebP. Choose Same as original for a PNG, or pick WebP, which supports transparency and usually produces a much smaller file. Avoid JPG for logos and cutouts, because JPG has no transparency and fills transparent areas with a solid color.

PNG is a lossless format, so the quality slider has little effect on it. To make a PNG smaller, set a maximum width or switch to WebP.

Convert and Compress PNG to WebP Online Free

Converting PNG to WebP is one of the fastest ways to cut image weight on a website. Select WebP as the output format, keep the quality around 80 and compare the before and after sizes shown under the tool. Most screenshots, icons and illustrations become far smaller while keeping their transparency.

WebP is supported by all current major browsers, so it is safe for most websites and blogs.

Lossless JPEG Compressor Online Free No Sign Up

Strictly lossless JPEG compression needs special tools that rewrite the file without re-encoding it. This tool re-encodes the image, so it is a quality-controlled compressor, not a lossless one. For results that are close to the original, set the quality between 90 and 95. For the smallest size with little visible difference, use 70 to 80.

You never need an account, and your picture stays on your device.

Bulk WebP Image Compressor Online Free

This tool handles one image at a time, which keeps it fast and reliable on phones and low-memory devices. To prepare many images, run them one after another with the same settings. Choosing WebP and a quality near 80 for each file gives consistent results across a whole set.

Compress AVIF Image Online Free High Quality

If your browser can open an AVIF file, you can load it here and export it as WebP or JPG at the quality you choose. This tool does not create AVIF files, so it is best used to convert AVIF images into formats that work everywhere. Keep the quality at 85 or higher when you want high visual quality.

Compress Transparent PNG Online Free High Compression

For maximum compression of a transparent image, use WebP with a quality of 60 to 75 and set a smaller maximum width if the image is displayed small. A logo shown at 300 pixels wide does not need to be 2000 pixels wide. Together, these two steps often cut the file size by more than half without touching transparency.
