Image Compressor

Yes — free, unlimited batches, no signup, no watermark.

No. This image compressor runs entirely in your browser — you can watch the Network tab while you compress and you will see no upload of your images. Tools that need server processing are labeled separately and ask before uploading.

Usually yes, and each row shows the real before-and-after size — we don’t promise a percentage up front because the honest answer depends on the image. If an image is already well compressed, the tool keeps your original and marks it as already optimized rather than handing you a bigger file.

PNG is a lossless format, so recompressing it may barely change its size — sometimes it doesn’t shrink at all. The tool tells you when that happens and keeps your original. If you want a PNG genuinely smaller, converting it to WebP usually helps, which the format switch does in one click.

Recommended 80 is the everyday setting — visually indistinguishable for most photos at a much smaller size. Balanced 60 squeezes harder for web thumbnails and previews. Extreme 40 is for when size matters more than fidelity. The slider lets you fine-tune any value between.

Re-encoding strips EXIF and GPS metadata — camera model, location and timestamps don’t carry over. If the tool keeps an already optimized original instead, that file is unchanged and its metadata stays with it. Do not use this compressor as a guaranteed metadata remover.

Yes — flip the output switch to Convert to WebP and every image is re-encoded as WebP, which usually makes it smaller still. If your browser can’t encode WebP, the switch is disabled and your output simply stays in the original format.

JPEG (JPG), PNG and WebP files in, JPEG/PNG/WebP out. HEIC photos: convert them with our HEIC to JPG tool first. Large photos take a moment — big images are re-encoded at high quality, which takes a second or two each.

Add the JPEG, choose a quality level and download — re-encoding at Recommended 80 drops the bytes most photos don’t need. Each row shows the real before-and-after size, so you can see exactly how much smaller the file got before you keep it.

Compress it first, then read the size on each row — mail providers usually cap the whole message somewhere around 20–25 MB. Balanced 60 or Extreme 40 brings a phone photo down into the low hundreds of KB, and the WebP switch usually shrinks it further.

Not as a fixed target — we won’t promise a number we can’t keep. Drag the quality slider and watch the size update on each row until it lands where you need it, then download that file. For a target size, try our Compress Image to KB tool, which automatically adjusts quality and may resize the image to meet the limit.

To compress JPG images aggressively, choose a lower quality setting — Extreme 40 is the lowest quality preset — and try Convert to WebP. Each row shows the real before-and-after size, so you can raise the quality if the image looks too rough.
