Image Compressor

Shrink JPG, PNG, WebP, AVIF, GIF and SVG images, one at a time or hundreds at once. You can also resize them and convert between formats. Everything happens in your browser, so your images are never uploaded.

Lower means smaller files. For PNG, 95+ is lossless.
Resize (optional)
px
Keeps the aspect ratio and never enlarges.

Why compress images

Photos straight from a phone are often 3–8 MB, far more than most uses need. Large files hit upload limits and slow websites down. Many job portals and government application forms cap photo, signature and document uploads at a few hundred kilobytes, sometimes less. Email attachments bounce above 20–25 MB. Compressing first avoids all of that.

For HR teams, it also helps when collecting employee photos, ID proofs and certificates. Smaller files upload faster, take less storage and still print clearly.

Choosing a format

JPG
Photos. No transparency. Opens everywhere.
Best for photos
PNG
Screenshots, logos, text and anything with transparency.
Best for graphics
WebP
Typically 25–35% smaller than JPG at similar quality, with transparency support.
Best for websites
AVIF
Smaller still, but slower to create. Not every browser can save it.
Smallest files
SVG
Vector graphics. Cleaned of comments and metadata without any loss.
Icons and logos

How the quality setting works

Formats that get converted

Browsers cannot save GIF, BMP, TIFF or HEIC files. With "Same as original" selected, those are saved as PNG if they have transparency and as JPG otherwise. Animated GIFs become a still image. HEIC and TIFF files can only be opened in Safari.

Your images never leave your device. Compression runs entirely in this browser tab using its built-in image encoders. Close the tab and every image is gone.

Frequently asked questions

Are my images uploaded to a server?

No. Every image is compressed inside your browser using its built-in image encoder, so nothing leaves your device. That makes the tool safe for ID proofs, signatures and other private documents. It also works on a slow connection once the page has loaded.

Which image formats can I compress?

JPG, PNG, WebP, AVIF, GIF, BMP and SVG in every modern browser. HEIC and TIFF files open only in Safari, because other browsers cannot read them. You can also convert between formats, for example PNG or JPG to WebP.

How many images can I compress at once?

Up to 200 images per batch, each up to 50 MB. Drop them all in together, adjust the quality once, and download the results individually or as a single ZIP file.

Will compression reduce image quality?

JPG, WebP and AVIF compression is lossy, but at the default quality of 75 the difference is hard to see while the file is usually far smaller. PNG is compressed by reducing the number of colours, which works very well for screenshots, logos and graphics. Set quality to 95 or above for lossless PNG. SVG files are cleaned without any loss.

What happens to photo metadata such as location?

Compressed images are re-encoded from scratch, so EXIF metadata such as camera details and GPS location is removed. Photos are rotated the right way up first. If an image was already optimised and the original is kept, its metadata is unchanged.

Why did an image get bigger, or stay the same?

Some images are already heavily optimised, and re-encoding them cannot make them smaller. With "Keep the original if it doesn't get smaller" ticked, the tool gives you back the original file untouched in that case. Converting to a different format or resizing always produces a new file.
