Large photos slow down product pages, fail to upload to forms and fill up email attachments. This free image compressor makes your JPG, PNG and WEBP files smaller in your browser, to the exact file size you need or to the quality you choose.

Compress to an exact file size

Choose 20, 50, 100, 200 or 500 KB, 1 MB, or any size. The tool searches for the best quality that fits, and only reduces the pixel size when quality alone is not enough.

Faster product pages

Smaller photos load faster, which shoppers on phones notice. For store photos, 200-500 KB at 2000 px is usually plenty; set a longest side as well if your photos are straight from a camera.

JPG, PNG and WEBP

JPG is best for photos. WEBP is smaller than JPG at the same look and keeps transparency. PNG is lossless, so the size target is reached by making it smaller in pixels.

Never bigger than before

If a photo is already well compressed, the tool keeps your original instead of handing back a larger file.

FAQ

Image Compressor: questions sellers ask

How do I compress an image to 100 KB?

Pick the photo, keep "100 KB" selected and press Compress. The tool finds the highest quality that fits under 100 KB. If even a low quality is too big, it reduces the pixel size step by step until the file fits, and tells you the new size.

Can I compress to 20 KB or 50 KB for a form?

Yes. Pick 20 KB or 50 KB, or choose Other and type any size. For very small targets the photo will also get smaller in pixels, which is normal for online forms that ask for a small file.

Why is my PNG still large?

PNG keeps every pixel exactly, so it cannot be squeezed much by quality. With "Same type" selected, a PNG is saved as WEBP, which is much smaller and still keeps transparency. If you must keep PNG, the tool reaches the target by reducing the pixel size.

Does compressing reduce quality?

JPG and WEBP compression removes detail you mostly cannot see. At 70-85% quality most product photos look the same on screen. Very small targets (20-50 KB) will show some softness.

Can I compress many images at once?

Yes. Pick up to 50 images and download them all in one ZIP. Each one shows its old and new size.

Are my images uploaded?

No. Compression happens in your browser, so nothing is sent anywhere.

Can I rename the compressed images?

Yes. Type a name in the "File name (optional)" box under the results before you download. One image gets that name. Several get name-1, name-2 and so on, also inside the ZIP. The file ending, such as .jpg or .webp, is kept.

Is Z Product AI really free?
