Understanding Image Formats
Digital images come in dozens of formats, but three dominate everyday use: JPG, PNG, and HEIC. Each was designed with different priorities—file size, quality, transparency, or device compatibility—and picking the wrong one can mean blurry logos, bloated web pages, or photos that won't open on a colleague's computer.
JPG (JPEG) uses lossy compression to keep file sizes small, making it the default choice for photographs and web images. It is supported by virtually every device and platform. However, it does not support transparency and loses a small amount of detail each time you re-save it.
PNG uses lossless compression, so no detail is lost no matter how many times you edit and save. It supports full transparency through an alpha channel, making it essential for logos, icons, screenshots, and any graphic with text or sharp edges. The trade-off is larger file sizes compared to JPG.
HEIC is Apple's modern format, used by default on iPhones and iPads since iOS 11. It produces files about half the size of equivalent JPGs with equal or better quality. The limitation is compatibility: most Windows programs, Android apps, and websites still do not accept HEIC uploads, so you need to convert to JPG before sharing outside the Apple ecosystem.
Available Image Tools
JPG to PNG
Convert JPG photos to PNG format for lossless quality and transparency support.
PNG to JPG
Convert PNG images to JPG for smaller file sizes, ideal for photos and web uploads.
HEIC to JPG
Convert iPhone and iPad HEIC photos to universally compatible JPG format.
Compress Image
Reduce image file size while preserving visual quality for faster loading and sharing.
Choosing the Right Image Tool
Need transparency for a logo or graphic? Use JPG to PNG. PNG supports an alpha channel, so you can place your image on any background without a white box around it. This is essential for website headers, watermarks, and overlays.
Need a smaller file for web or email? Use PNG to JPG. JPG files are typically 3-5x smaller than equivalent PNGs for photographs. If transparency is not required, JPG is almost always the better choice for photos.
Sharing iPhone photos with non-Apple users? Use HEIC to JPG. This ensures your photos open on any device, any operating system, and can be uploaded to any website or social platform.
Image too large to upload or share? Use Compress Image. This reduces file size without changing the format, which is useful when you need to stay under upload limits or speed up page loading.

Tips for Better Image Conversions
- →Converting JPG to PNG will not recover lost detail. JPG compression discards image data permanently. Converting to PNG preserves whatever quality remains and adds transparency support, but it cannot restore what was already lost.
- →Use PNG for anything with text or sharp edges. JPG compression creates visible artifacts around text and high-contrast edges. Logos, screenshots, diagrams, and infographics should always be PNG.
- →Use JPG for photographs. Photos contain millions of subtle color gradients where lossy compression is nearly invisible. A high-quality JPG photo looks identical to PNG at a fraction of the file size.
- →Avoid converting the same image multiple times. Each lossy conversion (JPG, HEIC) removes a bit more detail. Keep your original file and convert from that source whenever you need a new format.
- →Change your iPhone settings if you always share with non-Apple users. Go to Settings > Camera > Formats and select "Most Compatible" to shoot in JPG by default, avoiding the need to convert HEIC later.
