Examples

Quality 70, JPG, max width 1280 px. Small enough to send many at once.

About this tool

Large photos slow down websites, fill up inboxes and hit upload limits. This compressor re-encodes your images at a quality level you choose and can also scale down oversized pictures, which is usually where the biggest savings come from. A 12-megapixel phone photo resized to 1600 px wide and saved as WebP at quality 75 often shrinks from 4 MB to under 300 KB with no visible difference.

Everything runs inside your browser using the built-in image encoder, so even private photos are safe to compress. Images are never uploaded, and you can compress dozens at a time.

Tip: WebP gives the smallest files and works in every modern browser. Use JPG when you need maximum compatibility, and PNG for screenshots or graphics with sharp edges and transparency.

This tool runs entirely in your browser. What you type or open is never sent to a server.

Frequently asked questions

Will compression reduce quality?

JPG and WebP compression is lossy, but at quality 70-85 the difference is practically invisible. Lower values give smaller files with more visible artifacts. PNG is lossless, so resizing is the main way to shrink it.

Are my images uploaded?

No. Compression happens on your device with your browser's own image engine. Nothing is sent to any server.

Why did a PNG get bigger?

PNG is lossless, so re-saving a well-optimized PNG can come out slightly larger. With "Keep original if result is bigger" on, you get the original back. Converting to WebP usually helps a lot.

Is there a file size or count limit?

No limits from us. Very large images (50+ megapixels) depend on your device memory.

Does it keep EXIF data like location?

No. Re-encoding strips EXIF metadata, including GPS location, which is good for privacy when sharing photos.
