Image Compressor

Compress JPEG, PNG, WebP and iPhone HEIC images directly in your browser: one photo with a live before/after preview, or a whole folder at once with a single ZIP download. Reduce file size by up to 80%, cap the pixel size for even smaller files, and keep the date taken. No upload, no sign-up and no file limit.

How to use the Image Compressor

  1. Add your images: Drop, paste (Ctrl+V) or browse for one or many JPG, PNG, WebP, HEIC, GIF or AVIF images. They load into browser memory. Nothing is uploaded and there's no file-count limit.
  2. Choose quality, size and format: Pick a quality preset (Balanced 80% suits most photos) and, for big phone photos, a max size such as 1920 px. Choose JPG for compatibility or WebP for the smallest file.
  3. Compare & download: Check detail with the before/after slider, then download one file or everything as a ZIP. If a file can't get smaller, you get the original back, never a bigger file.

Frequently Asked Questions

How do I compress an image online for free?

Drop your JPG, PNG, WebP or HEIC image into the compressor, adjust the quality slider (80% is a great balance) and watch the live preview update. Click Download to save the result. Nothing is uploaded to any server.

Can I compress many images at once?

Yes. Drop as many images as you like. There's no 20-file cap, no size cap and no daily limit. The same settings are applied to every image on your device, and you can download them one by one or all together as a ZIP.

Why did my image get bigger after compressing it?

Photos that are already heavily compressed can grow when they're re-saved. ImgConvertPro checks this: if the result would be larger than your original, you get the original file back unchanged. To shrink it further, choose a max size (e.g. 1920 px). Reducing the pixel size is the biggest saving for phone photos.

Will compressing an image reduce its quality?

JPEG compression is lossy, but at 70–85% quality the difference is virtually invisible. For graphics with text or sharp edges, use Compress PNG, which keeps edges crisp.

Does compressing remove the date and location from my photos?

By default the date taken and camera info are kept in JPG output, so your gallery still sorts the photo correctly, while GPS location is removed for privacy. You can switch either off or on before downloading.

What is the best quality setting?

For web photos, 75–85% gives the best size-to-quality ratio: typically 50–70% smaller with no noticeable loss. For print, stay at 90% or above.

How much can I reduce a file's size?

Typically 40–80%. A 5MB phone photo often drops below 500KB at 80% quality, and well below that with a 1920 px max size.
