Image Compressor
Choose a target size or encoding quality for JPEG/WebP. Process locally, keep dimensions, check bytes, and download. A smaller file is not guaranteed.

Quick answer: Toolars Image Compressor does the same job — reducing PNG, JPEG, and WebP file size — without the upload. Compression runs locally in your browser, accepts batches of up to 12 files, and shows exact before-and-after byte counts. Pair it with the Image Resizer and Format Converter for the full TinyPNG-plus workflow.
TinyPNG is a long-running online image compressor for PNG, JPEG, and WebP files. It works well, but it is a cloud service at its core: you upload each image to TinyPNG's servers, which compress it and hand it back. Free usage is limited to a small number of images at a time, and larger or automated workflows are pointed at a paid API or subscription.
| TinyPNG | Toolars | |
|---|---|---|
| Privacy | Every image is uploaded to TinyPNG's servers for compression | Images are compressed locally in your browser — nothing is uploaded to a server |
| Free tier | A limited number of images per session; larger volumes need paid plans or the API | Free with no image count limits |
| No sign-up | No account for casual use, but limits push power users to sign up | No account or email required — open a tool and start |
| No upload | Compression happens on their servers, not your device | There is no upload step; images stay on your device |
| Batch | Small per-session batch size on the free tier | Compress up to 12 images per batch, repeatedly |
| Offline | Requires an internet connection for every image | Processing is local, so the task runs without a network once the tool has loaded |
