Best free image compressors compared: SaveForMeNow, TinyPNG and Squoosh
Short answer: for many images at once with simple settings, use a batch tool such as the SaveForMeNow image compressor (up to 50 images) or TinyPNG (up to 20 images, 5 MB each). For fine control over one image, Squoosh is excellent. All three are free for everyday use.
We make one of these tools, so we've stuck to facts you can check on each site. We checked the limits on 29 October 2026. Services change, so check the current limits before you rely on them.

When to pick each one
SaveForMeNow
Best when you have a folder of photos for a website, shop or form and want them smaller in one go. Target size is useful for upload limits such as "under 200 KB". Compression runs in your browser. Guide: how to compress images and compress an image to a specific size.
TinyPNG
A long-running, simple tool. You drop images and it picks the settings for you. It's a good fit if you want zero decisions and have fewer than 20 small files. For bigger batches or files over 5 MB, you need its paid plan.
Squoosh
An open-source app from Google Chrome Labs. It handles one image at a time but shows exactly what each setting does, with a slider to compare the original and the result. It's ideal for a hero image you want perfect, or for learning how codecs behave.
What matters more than the tool
The tool matters less than these four habits:
- Resize to the size it's displayed at. A photo shown 1200 pixels wide doesn't need 4000 pixels. Use the image resizer.
- Pick the right format. Use WebP or AVIF for photos on websites, PNG for logos and screenshots, and SVG for icons. See WebP vs JPG vs PNG and AVIF vs WebP.
- Don't compress twice. Every lossy save loses a little more. Always start from the original.
- Check on a phone. Artefacts that are invisible on a laptop can show up on a high-density phone screen, and so can the other way round.
A quick test you can repeat
To compare tools fairly, use the same original photo, aim for the same visual quality and compare the file sizes. In our test, a 1.8 MB 4000 × 2250 JPG became 671 KB on the Recommended level and 358 KB when saved as WebP. Your results will vary with the photo.
Questions
Which compressor gives the smallest files?
It depends on the image and the format more than on the tool. Photos saved as WebP or AVIF are usually smaller than JPG at the same quality, whichever tool you use.
Is it safe to compress private photos online?
Pick a tool that processes files in your browser, or read the tool's privacy policy. SaveForMeNow's image tools run on your device. See how browser-based tools keep your files private.
Does compression remove EXIF data?
SaveForMeNow saves compressed copies without EXIF data. Other tools vary. To be sure, use the EXIF remover.
