Compress images online without losing quality

Drop your photos below and CompressEasy shrinks them right in your browser. JPG, PNG, WebP, AVIF and JXL are re-encoded with tuned WebAssembly codecs, so a 4.8 MB product photo becomes a 620 KB file that still looks sharp on a Retina screen. Nothing is uploaded, there is no watermark and you can process a whole folder at once.

Output defaults to WebP for the best size-to-quality ratio. Switch to JPEG, PNG, AVIF or JXL above if you need a specific format.

How it works

  1. Drag your images into the upload area above, or click to select them.
  2. Pick the output format if needed — WebP by default, or JPEG, PNG, AVIF and JXL.
  3. Review how much each file shrank and download single images or the whole batch.

Why compress images?

Camera and phone photos are far larger than any screen can show. Oversized images slow down websites, hurt Core Web Vitals, blow through email attachment limits and eat storage. Compressing them keeps the same visual result at a fraction of the size, so pages load faster and uploads finish sooner.

Smaller files, sharp quality

CompressEasy picks a quality level where artifacts are hard to spot but the file gets dramatically smaller, typically 60–90% depending on the source. Photos with lots of detail keep their texture; screenshots and graphics with flat colors stay crisp instead of turning blurry.

Private, batch and unlimited in the browser

Everything runs on your own device using fast WebAssembly encoders. No file leaves your browser, so client work, product shots and personal photos stay private. Drop dozens of images at once and download them individually or as a single batch.

Frequently asked questions

Which image formats can I compress?

JPG/JPEG, PNG, WebP, AVIF and JXL as input. You can keep the same format or convert, for example PNG to WebP, while compressing.

Will compression reduce image quality?

Lossy formats like JPEG and WebP drop a small amount of detail, but CompressEasy targets a level where the difference is hard to notice on screen while the file shrinks by up to 90%. PNG output stays lossless.

Are my images uploaded to a server?

No. Compression runs entirely in your browser with WebAssembly. You can open the network tab while compressing: no request carries your images.

Is there a limit on file size or number of images?

You can drop many images at once and there is no per-file size limit beyond what your browser can hold in memory. The free plan includes a daily allowance; Pro removes it.
