Legacy formats
TIFF, BMP, and GIF: How to Convert Old Formats to Modern Files
Old image formats are still common in archives, scans, design handoffs, and legacy Windows folders, but they are not always friendly for modern websites and everyday sharing.
TIFF: archive first, share second
TIFF is common in scanning, print, photography, and archives. It can preserve high quality, but files are often large and not ideal for websites or email.
Keep TIFF as a master archive when quality matters, then export JPG for sharing, PNG for lossless previews, or WebP for web publishing.
BMP: convert almost every time
BMP files are usually uncompressed and heavy. For most practical uses, converting BMP to JPG or PNG gives a smaller, easier file without changing the visible content.
Use JPG for photo-like BMP files and PNG for screenshots, diagrams, or graphics with hard edges.
GIF: animation or legacy graphic
GIF is still useful for simple animation, but it is limited in color and can be large. For static GIFs, convert to PNG or WebP. For animated web use, WebP may reduce size.
If you only need one frame from a GIF, export PNG. If you need compatibility, keep GIF but compress and test the result.
Modern output choices
Choose JPG for photos, PNG for lossless graphics, WebP for most modern web images, and AVIF when you want maximum compression after testing.
- Photo archive: TIFF master plus JPG/WebP copy
- Old bitmap: BMP to JPG or PNG
- Static animation frame: GIF to PNG
- Website image: WebP or AVIF
