Compress to 1 MB without uploading anything

Drop your images and each one comes back at or below 1 MB, at the best quality that fits. Nothing is sent anywhere unless you ask for it.

Or click to choose them. Several at once is fine, and you can drop more later.

How the size is hit

An encoder takes a quality and answers with a size, never the other way round. So the page tries a quality, looks at the result and halves what is left to search, about nine times per image. Each row says which quality it settled on.

When quality is not enough

A large photo pushed towards a small target runs out of quality before it runs out of pixels. Below 30% the search stops lowering quality and starts shrinking the picture instead, which looks better at the same size. A row that still could not get there says so rather than pretending.

Where 1 MB is the limit

Many forums, older upload forms and email services still cap images at 1 MB. Modern phone photos are three to ten times that.

For the best result

A 12 megapixel phone photo fits into 1 MB at full resolution with quality to spare in most cases.

Questions people ask

How do I make a phone photo smaller than 1 MB?

Drop it here and it is saved as a JPG or WebP just under 1 MB, usually at full resolution.

Does it work with iPhone HEIC photos?

Only in Safari, which is the one browser that can open HEIC. Elsewhere, share or export the photo as JPG first.

Are my images uploaded to compress them?

No. Every attempt at the target size is encoded by your own browser, so the picture never leaves your device.

How does it hit the exact size?

An encoder takes a quality and answers with a size, never the other way round. The page tries a quality, looks at the result and halves what is left to search, about nine times per image.

What if the target is too small for the picture?

Below 30% quality the search stops lowering quality and shrinks the picture instead, which looks better at the same size. A result that still cannot get there says so.
