"Can't open HEIC files on Windows/Android"

Why HEIC?

Problem: Windows, Android, and most applications don't support HEIC.

Solution: Convert to JPG

"WebP images won't open in Photoshop/Windows Photo Viewer"

WebP is modern and web-optimized, but older software doesn't support it.

Why WebP?

Google created WebP in 2010 - it's 30% smaller than JPG with same quality. Great for websites!

Problem: Older Photoshop, Windows apps, and desktop software don't support WebP.

Solution: Convert to JPG/PNG

  • • WebP to JPG - Universal compatibility
  • • WebP to PNG - If you need transparency
  • • Result: Works in all applications

Tip: Modern browsers support WebP (97%). Only convert if you need desktop app compatibility.

"TIFF files are huge and won't upload to website"

TIFF files are uncompressed and massive (10-50MB). Not web-compatible.

Why TIFF?

TIFF (Tagged Image File Format) is used for professional photography and printing. Supports layers, high bit depth, no compression.

Problem: 10-50MB files, not web-compatible, limited browser support.

Solution: Convert to JPG

  • • TIFF to JPG Converter
  • • Size reduction: 50MB TIFF → 2MB JPG (25x smaller!)
  • • Quality: Visually identical at 85% quality
  • • Use: Web, email, sharing

Keep original TIFFs for archival/printing. Convert copies to JPG for digital use.

"RAW files won't open (CR2, NEF, ARW, etc.)"

Camera RAW files require specific software and camera profiles.

Common RAW Formats:

  • • CR2/CR3: Canon
  • • NEF: Nikon
  • • ARW: Sony
  • • RAF: Fujifilm
  • • ORF: Olympus

Problem: Proprietary formats, large files (20-50MB), require special software.

Solution:

  1. For editing: Use Adobe Lightroom, Capture One, or DxO PhotoLab (RAW-compatible)
  2. For sharing: Export RAW to JPG (universal compatibility)
  3. For archival: Convert to DNG (universal RAW format)

Workflow: Edit RAW → Export to JPG at 85-90% quality → Share JPG

🖥️

"BMP files are too large and outdated"

BMP (Bitmap) is uncompressed Windows format from 1990. Huge files, limited use.

Why BMP is Outdated:

  • • No compression (5-10x larger than JPG)
  • • Limited web support
  • • No metadata support
  • • Windows-centric format

Solution: Convert to JPG/PNG

  • • BMP to JPG - 10x smaller
  • • Size: 10MB BMP → 500 KB JPG
  • • Quality: Identical
  • • Use: Everything (universal)

"Need to convert SVG to PNG/JPG for compatibility"

SVG (vector) is great for web, but some apps need raster formats (PNG/JPG).

When to Convert SVG:

  • • Email signatures (many clients don't support SVG)
  • • Social media (require PNG/JPG)
  • • Presentations (PowerPoint, Google Slides)
  • • Print (need high-res raster)

Solution: Convert to PNG

  • • SVG to PNG Converter
  • • Choose output resolution (e.g., 2000px width)
  • • Preserves: Transparency, crisp edges
  • • Use: Universal compatibility

ICO files are Windows icons. Limited use outside of favicons/Windows.

When You See ICO:

  • • Windows application icons
  • • Legacy desktop software

Frequently Asked Questions

Why can't I open HEIC files on Windows?

HEIC (iPhone photos) isn't natively supported on Windows. Windows 10/11 can open HEIC with an extension, but it's easier to convert to JPG. Use Diwadi's HEIC to JPG converter for instant universal compatibility.

What's the most universal image format?

JPG is the most universal format - works on every device, browser, platform, and application since 1992. If compatibility is critical, convert to JPG. PNG is also universal and supports transparency.

Will converting formats reduce quality?

It depends. Lossless conversions (PNG→JPG, HEIC→JPG at high quality) maintain near-identical quality. Lossy→lossy conversions (JPG→WebP→JPG) can compound quality loss. Best practice: keep original files, convert copies.

Can I convert WebP back to JPG?

Yes! Use Diwadi's WebP to JPG converter. Quality will match the original WebP file. If the WebP was compressed from JPG, you won't get original JPG quality back (conversion is one-way).

Why won't my RAW files open in Photoshop?

RAW formats require specific camera profiles. Older Photoshop versions may not support newer cameras. Solution: Convert RAW to DNG (universal RAW) or JPG/TIFF for editing.

What if I need to keep transparency?

Use PNG format. JPG doesn't support transparency - converting PNG→JPG will replace transparent areas with white/black. For web with transparency, use WebP (supports transparency + smaller files).

Can I batch convert 100s of images at once?

Yes with Diwadi! Drag entire folders and convert all images to your target format simultaneously. Desktop tools like Diwadi process 100s of images in seconds. Online converters limit batches to 1-20 files.

Will converted images work everywhere?

If you convert to JPG or PNG, yes! These formats have 100% compatibility across all devices, browsers, and applications. For modern web use, WebP also works (97% browser support).
