Frequently asked questions

No. The compress, convert, resize and batch tools decode, process and re-encode images inside your browser tab. The image files never leave your device. If we add a feature that needs server processing, it will be clearly labelled before you use it.

No. All tools work without signing in. An account is only needed for a paid plan, which raises the limits.

Yes, in current mobile browsers. Phones have less memory than computers, so very large images or big batches can fail on a phone even within the plan limits.

Yes. Re-encoding drops EXIF metadata such as camera details and GPS location. Orientation is applied to the pixels first, so photos stay the right way up.

You can open JPG, PNG, WebP, AVIF, GIF (first frame only) and BMP. You can save as JPG, PNG and WebP in every supported browser, and as AVIF only if your browser can encode it; otherwise that option is turned off.

They aren't supported. Browsers can't reliably decode HEIC or TIFF, and SVG is a vector format that doesn't need this kind of compression. Pixnex recognises these files and tells you rather than producing a broken result.

Some images are already well optimised, and converting to a lossless format like PNG can add size. Pixnex always shows the real result, including increases, so you can try a different setting or keep the original.

Not unless you turn on the option to allow enlarging. By default, if you enter dimensions larger than the original, Pixnex keeps the original size and tells you.

No. Only the first frame of an animated GIF is processed.

Up to 20 images per batch and files up to 20 MB each. Paid plans raise these limits.

Not yet. An API is planned, and we'll only list it as a feature once it's available.

By UK bank transfer. When you choose a plan you get a payment reference and our bank details. Send the exact amount quoting the reference, then tell us you've paid.

As soon as we've confirmed the money has arrived in our bank account. We check by hand, so it can take longer outside working hours.

No. Nothing is ever charged automatically. When your period ends you return to the Free plan unless you pay again.

Check that you clicked “I've sent the transfer” on the payment page and quoted the right reference. If it's been more than two working days, contact us with your reference.

See the refunds section of our Terms of Service, or contact us with your payment reference.
