When should I use PNG, JPEG, or WebP?

Use PNG for graphics with transparency or sharp edges, JPEG for photographic images where small size matters, and WebP for modern browsers when you want smaller files at similar quality; fall back to PNG/JPEG if compatibility is required.

Does changing DPI affect image quality on the web?

No. On the web, pixel dimensions determine display size and sharpness. DPI (or PPI) only matters for print, where it maps pixels to physical inches or centimeters.

How do I keep transparency when converting from PNG?

JPEG does not support transparency. Keep PNG or convert to WebP (lossy or lossless) or AVIF to preserve the alpha channel; otherwise add a solid or checkerboard background before exporting JPEG.

What quality setting should I use for JPEG or WebP?

Start with JPEG quality 75–85 and WebP quality 70–80 for a good balance. Inspect artifacts on edges and gradients, then adjust by ±5 as needed; always compare final file sizes.

Will converting JPEG to PNG improve image quality?

No. A JPEG’s compression loss is irreversible. Converting to PNG increases size without restoring detail; only do it to add transparency or avoid further lossy degradation during edits.

How can I batch convert images reliably?

Use consistent presets and a scriptable toolchain, run a small test set first, and verify outputs for format, dimensions, and color profile. Keep backups so you can reprocess if requirements change.

How do I preserve EXIF and color profiles during conversion?

Enable metadata retention and embed the source or target ICC profile (often sRGB for web). Avoid options that strip EXIF/IPTC unless required, and verify profiles in the exported files.

Image Conversion Guides: Formats, Quality, and Automation

Key Takeaways

Actionable points curated for this category.

Choose the right format for the job

PNG for transparency and UI, JPEG for photos, WebP/AVIF for modern compression, SVG for vectors and logos, HEIC for iOS photos, TIFF for print or archival.

Control quality without bloating size

Use lossy vs lossless wisely, adjust quality and chroma subsampling, prefer progressive JPEGs for perceived speed, and measure with real page weights.

Preserve transparency and color accuracy

Keep alpha channels when needed, avoid unintended matte edges, embed the correct ICC profile, and convert to sRGB for web delivery.

Export differently for web and print

Match pixel dimensions to display needs; DPI affects print, not web. For print, use CMYK or a specified ICC; for web, stick to sRGB raster formats.

Automate batch conversions safely

Use repeatable presets and scripts, verify outputs with spot checks, and log failures. Keep originals so you can re-run with updated settings.

Handle metadata and compliance

Decide what to keep or strip: EXIF, IPTC, and XMP. Preserve copyright where required and remove sensitive location data when publishing.
