How much can it reduce the file size?

For photos (JPG/PNG of photos), expect 70–90% reduction at quality 75. For graphics and icons with flat colours, savings are smaller. WebP typically saves 30% more than JPEG at the same quality.

Which output format should I choose?

Choose JPEG for the smallest files — best for photos shared by email or web. Choose WebP for modern browsers with excellent quality. Choose PNG only if you need lossless output or transparency.

What image formats are supported as input?

JPG, JPEG, PNG, WebP, GIF, BMP, AVIF, TIFF and TIF are all accepted.

Will the image dimensions change?

No — the image dimensions stay exactly the same. Only the encoding quality and format change.

Can I compress multiple images at once?

Yes — drop or select as many images as you like. All are compressed and available as individual downloads or a single ZIP.

Is the original file modified?

No — your originals are never touched. Compressed copies are downloaded to your device.

Why is my PNG file not getting smaller?

PNG is a lossless format — the PNG output option repackages the image without quality loss. For PNG files, convert to JPEG or WebP output to see significant size reductions.

What quality setting should I use?

70–80 is the sweet spot for most photos — gives excellent visual quality with 70–90% file size reduction. Go higher (85–95) for client-facing images where quality is critical.

What is Image Compressor?

Image Compressor reduces the file size of any image format — JPG, PNG, WebP, GIF, BMP, AVIF and more. Output as JPEG (smallest), WebP (best quality-to-size), or PNG (lossless). Achieves up to 90% size reduction on typical photos.

How It Works

Drop your images, pick an output format and quality level. The tool re-encodes each image using the browser's native canvas engine — no server upload, no third-party processing. JPEG and WebP compression is lossy but virtually indistinguishable at 70–80% quality. PNG output is lossless. Each image is processed individually so you get maximum compression.

How to Use

Drop one or more images (JPG, PNG, WebP, GIF, BMP, AVIF, TIFF) onto the upload zone or click to browse.
2
Choose output format
Select JPEG for the smallest files, WebP for best quality-to-size ratio, or PNG for lossless output.
3

4
