Image Optimizer: a photo optimizer in your browser

Optimize a JPEG, PNG, or WebP photo in your browser. Set a quality level or an exact file size, convert to WebP, or process a batch. Files are processed locally and are not uploaded. Practical starting points: a website hero often lands around 200–500 KB, an article image around 100–200 KB, a thumbnail under 100 KB, and an email photo around 200 KB–1 MB.

Questions

Does this image optimizer upload my photos?

No. Compression runs in your browser. SnapCompress does not receive the image file in order to compress it. You download the result on this device.

What can I change on this page?

Single Image has a quality slider and an exact file-size target. Presets are 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, and 2 MB, and you can type another KB budget. Output can be JPEG, PNG, or WebP. Multiple Images uses that same quality slider and those formats. Free batches allow up to 5 images, and Free files can be up to 8 MB.

Are camera data and location tags removed?

A re-encoded download does not copy EXIF, so GPS and camera tags are left out. Keep EXIF metadata is a Pro option, and it applies only when you are not cropping. If the new file would be larger than the original and you are not converting or cropping, the original file is returned and its metadata stays.

Should website photos be WebP?

WebP is usually the smallest choice for a photo. Use JPEG when a CMS or an older mail app will not display WebP. PNG fits flat graphics and transparency, but it has no quality dial, so a photograph saved as PNG often stays large.

What size should a hero, blog image, or thumbnail be?

Treat these as starting points, not requirements. A full-width hero often works around 200–500 KB, an article image around 100–200 KB, and a thumbnail under 100 KB. On a single image, open Compression Settings, choose To exact size, and enter that budget. Pixel dimensions shrink only when quality alone cannot fit. Choosing a width or an aspect-ratio crop is a Pro control.

Can I optimize more than one photo?

Yes. Switch to Multiple Images. Free batches include up to 5 images. Pro has no plan-level batch cap, and device memory is the practical limit. Batch mode uses the quality slider. The exact KB target is on Single Image.

Do I need an account?

No. Guests can compress 10 images a day, and a free account raises that to 50. There is no watermark. Pro removes the daily cap and raises the per-file limit to 50 MB.
