About these tools

Photo won’t open? Too big to email? Wrong size for Instagram? These tools fix the everyday problems with images, for free, in a few seconds.

Converting fixes files that won’t open. iPhones save photos as HEIC, which Windows and many Android phones can’t open, and pictures saved from websites often come as WEBP, which many apps reject. Turning them into JPG or PNG solves it.

Compressing and resizing make files smaller. Resizing cuts the number of pixels and usually saves the most. Compressing trims detail you won’t notice. Together they can take a phone photo from a few megabytes down to a couple of hundred kilobytes, with no visible difference on screen.

Every tool works right on your device, so your photos are never sent anywhere — and there’s no waiting in a queue.

Questions people ask

Can anyone else see my images?

No. Every tool works on your device, so your images are never sent anywhere. Each tool shows a counter to prove it: 0 bytes sent.

Is there a size or number limit?

No limit from us. Very large batches may just be slower on older devices.

Which formats work?

JPG, PNG, and WEBP everywhere, plus iPhone HEIC photos in most tools.

Should I compress or resize?

Resize first if the image is bigger than it will be shown — that saves the most. Then compress if it still needs to be smaller.

Do you add a watermark?

Never. No watermarks, no sign-up, and no limits.
