How do I compress images on Mac without Photoshop?

Use FixTools in any Mac browser. Upload your image, adjust the quality slider, and download the compressed version. No software installation required.

Can macOS Preview compress images?

Preview can reduce file size by exporting at lower quality ("Export" > choose quality). However, the quality control is less precise than FixTools, and Preview does not show real-time file size feedback.

Does Safari on Mac support drag-and-drop image upload?

Yes. You can drag an image from Finder directly onto the FixTools upload area in Safari or Chrome on Mac.

Can I compress HEIC images on Mac?

Yes. macOS handles HEIC files natively. Upload a HEIC file and FixTools will compress it. You can also convert HEIC to JPG using the Format Converter.

Is FixTools better than macOS Preview for image compression?

FixTools gives more control — you can see the output file size in real time and preview the quality before downloading. Preview exports at a fixed quality with no real-time feedback.

What happens to the original file on Mac?

The original is unchanged. FixTools downloads a new compressed copy to your Downloads folder. You can keep or delete the original.
