The Honest Take

TinyPNG is a classic. It's been around since 2014 and does PNG/JPEG compression really well. Their smart lossy compression for PNGs is genuinely impressive—they figured out how to reduce colors while keeping images looking great.

What TinyPNG nails: Dead simple interface, excellent PNG optimization, and they've been reliable for a decade. That kind of track record matters.

Where we do things differently: We support modern formats like WebP, AVIF, and PDF out of the box. We handle much larger files and images (up to 10,000×10,000 pixels free, 50,000×50,000 on Pro—great for infographics). We've got a full image editor with crop, rotate, brightness, contrast, saturation, sharpening, and rounded corners. Pro users get advanced controls for metadata, DPI, chroma subsampling, colourspace, and watermarks.

Mobile-friendly: Our entire interface works on phones. Take a photo, optimize it, post to your blog—all from your pocket, no app needed.

The honest take: If you compress a lot of PNGs and their 20 images/day limit works for you, TinyPNG is great. If you need more formats, larger images, editing tools, or want to work from your phone, we've got you covered.

Frequently Asked Questions

For JPEGs, results are nearly identical. For PNGs, TinyPNG's proprietary algorithm is specifically tuned for PNG optimization and it's excellent. We use libvips/Sharp which produces great results, but if PNG compression is literally the only thing you care about, TinyPNG has years of refinement there.
TinyPNG gives you 20 images/day, 5MB max file size. imgfast gives unregistered users 5 images/day (enough to try it out), but if you create a free account—takes 30 seconds, no credit card—you get 50 images/day, 20MB files, and images up to 10,000×10,000 pixels. Paid tiers go up to 1000/day and 50,000×50,000px.
Yes—crop, rotate, flip, adjust brightness/contrast/saturation, add sharpening or blur, and even rounded corners (including Apple-style squircles). Pro users can also add watermarks and control metadata. TinyPNG is compression-only.
Absolutely. The whole interface is optimized for mobile. Bloggers and content creators use it to take a photo, optimize it, and upload directly—no desktop or app needed. TinyPNG works on mobile too, but our editor and advanced features are fully touch-friendly.
