A TinyPNG alternative that never uploads your photos
TinyPNG (by Tinify) is one of the best-known web image compressors, and its smart compression is often excellent, especially on PNGs. If you also need to hit an exact KB limit, go past 20 images in a sitting, or keep ID photos and form uploads on your device, the Cuelark compressors do the work in your browser.
TinyPNG and Cuelark compared
| Feature | TinyPNG | Cuelark Tools |
|---|---|---|
| Price (web tool) | Web Free $0; Web Pro $3.25/month billed annually; Web Ultra $12.42/month billed annually (as shown on 10 Nov 2026) | Free |
| Free-plan limits | Up to 20 images per session, 5 MB each; up to 3 format conversions per session; standard speed; ads; no folder uploads | No session cap and no 5 MB upload cap, because nothing is uploaded |
| Where images are processed | Uploaded. TinyPNG says only you have access, they retain images for a maximum of 48 hours, then delete them | Files stay in your browser; nothing is uploaded |
| Compress to an exact size | Smart compression to a smaller file; exact KB targets are not the main offer | Exact targets such as 20 KB, 50 KB and 100 KB for exam and job forms, or any size |
| Formats | AVIF, JPEG XL, WebP, PNG, JPEG, HEIC and SVG on the web tool | Reads JPG, PNG, WebP, HEIC and AVIF; writes JPG, PNG and WebP (not AVIF, JPEG XL or SVG) |
| API and plugins | Developer API: first 500 compressions/month free, then $0.009 each up to 10,000/month and $0.002 above that; official WordPress and Figma plugins, Image CDN, website analyzer | No image-compression API. Other Cuelark APIs live on render.cuelark.com |

When TinyPNG is the better choice
TinyPNG's compression, especially on PNG, is often smaller than a generic browser encoder at the same visual quality. It also writes AVIF, JPEG XL and SVG, has a mature API, WordPress and Figma plugins, an Image CDN and a website analyzer. Choose it when you want the smallest web assets or a production pipeline.
Try it here
This is the same Compress image tool as the standalone page. Your file stays in this browser tab and is never uploaded. If scripts are off, open Compress image.
At 100 KB the detailed sample shrank from 2400×1600 to 1005×670 at quality 79. Set Max width to 800 to keep quality 90 at 800×533 instead. Under 100 KB is a ceiling of 100,000 bytes, not a portal's minimum. If the result is under the minimum on the form, this tool will not pad it.
Frequently asked questions
Will Cuelark make a smaller file than TinyPNG?
Not always, and often not on PNG. TinyPNG uses a specialised compressor that is well known for shrinking PNGs. Cuelark uses the browser's own encoders and aims for a target size you set. For a website full of PNGs, try TinyPNG (or Squoosh) as well and keep the smaller good-looking result.
Are my photos uploaded?
No. They are decoded and re-encoded in this tab. TinyPNG, by contrast, uploads images and says it deletes them within 48 hours.
Can I go past 20 images without paying?
Yes. There is no session cap here, because the work runs on your device.
Can I hit a 20 KB or 50 KB form limit?
Yes. Use Compress image to 20 KB or 50 KB. The tool aims for the highest quality that stays at or under that byte count (1 KB = 1,000 bytes, and a file that size also passes a 1,024-byte kilobyte check).
