- Are my images uploaded?
- No. Compression runs in your browser via Web Workers; files never leave your device.
- How much do I save?
- Typically 40–80%, depending on format and content. Photographs compress far better than flat graphics.
- Does quality suffer?
- Auto mode targets a quality where the difference isn't visible. Use the compare slider to check before downloading.
- What about animated GIFs?
- We handle the first frame of static GIFs and convert to PNG or JPEG. Animation isn't supported yet.
- Is transparency kept?
- Yes for PNG, WebP, and AVIF. JPEG has no alpha channel, so the background is filled white.
- What are the limits?
- 25 MB per image and 30 images per batch, to protect browser memory.
- Do I need an account?
- No. No sign-up, no email, no card. Open the page and use any tool. We keep nothing about you because we receive nothing in the first place.
- Is it completely free?
- Yes, with no watermark and no daily cap. Processing happens on your own device, so it costs us no servers to charge for. Ads cover the running costs.
- How do I set a custom quality?
- In the settings panel choose Custom quality and move the slider between 1 and 100. Or pick No compression if you want to change dimensions or format without touching quality.
- How is this different from TinyPNG or iLoveIMG?
- Those upload your images to their servers and send them back. We upload nothing — hence no queue, no daily cap, and no question about what happens to your files afterwards. We also support AVIF, icon generation and PDF conversion.
- Do you support HEIC from iPhone?
- Not yet. Desktop browsers cannot decode HEIC, and bundling a decoder would slow the page for everyone to serve a few. Set your iPhone camera to Most Compatible and you will get JPG.
- Does it work offline?
- Once the page has loaded, processing needs no connection because it all happens locally.
- Where are my statistics stored?
- In your browser's local storage alone; they never leave your device. Reset them from the usage dashboard whenever you like.
- Can I use it on mobile?
- Yes, on iPhone and Android straight from the browser with nothing to install. Very large batches can be slower on an older phone, since processing uses device memory.
