What This Tool Does

Convert any image to JPEG, PNG, WebP, AVIF, TIFF, GIF, or BMP — and back — directly in your browser. Up to 50 files per batch, mixed input formats supported, downloaded individually or as a single ZIP. Each format has a different sweet spot: JPEG is universal but lossy; PNG is lossless and supports transparency but produces large photographs; WebP and AVIF combine modern lossy compression with full transparency and are 25% to 50% smaller than the JPEG/PNG equivalent at the same perceived quality; TIFF is preferred for archival; GIF remains useful only for short looping animations and exotic legacy palettes.

When to Use This Tool

Convert legacy photos to WebP or AVIF when publishing to a modern website — both formats have ≥97% global browser support today and produce dramatically smaller payloads than JPEG. Convert to PNG when you need transparent backgrounds, lossless graphics, or compatibility with tools that don't accept WebP. Convert to JPEG only when the destination requires it (some print labs, ancient CMSes). Avoid converting between lossy formats repeatedly — every JPEG-to-WebP-to-JPEG round trip costs visible quality.

How to Use

  1. 1

    Drop your source images

    Add up to 50 files. The converter detects each input format automatically — you don't need to select it.

  2. 2

    Pick the output format

    Choose from JPEG, PNG, WebP, AVIF, TIFF, GIF, or BMP. WebP is the best general-purpose choice for the web in 2026.

  3. 3

    Set quality (lossy formats only)

    For JPEG, WebP, and AVIF, set quality between 75 and 90. PNG and TIFF are lossless and ignore the quality slider.

  4. 4

    Download converted files

    Each file shows the size before and after. Download individually, or use 'Download all as ZIP' to grab the entire batch.

Frequently Asked Questions

Which format gives the smallest file size?

AVIF typically provides the smallest files, followed by WebP. Both offer significantly better compression than JPEG while maintaining excellent quality.

Can I convert multiple images at once?

Yes. Upload up to 50 images and convert them all to the same format in one batch.

Will I lose quality converting PNG to JPEG?

JPEG is lossy and does not support transparency. At quality 90+ the visible loss is minimal, but transparent areas will be filled with white. Consider WebP if you need lossy compression with transparency.

Does conversion preserve EXIF and color profiles?

EXIF metadata is preserved when both source and destination support it (JPEG, TIFF, WebP). PNG and modern formats may not carry every EXIF tag. ICC color profiles are preserved for JPEG and PNG.

Can I convert HEIC photos?

Yes. HEIC and HEIF inputs are decoded automatically. For HEIC-specific guidance, the dedicated HEIC to JPG tool has additional iPhone-friendly defaults.

Pro Tips

  • AVIF beats WebP on file size by 10% to 30% but encoding is slower in the browser. For large batches under time pressure, WebP is the pragmatic choice.
  • When converting PNG screenshots to JPEG, use quality 90 or higher — JPEG handles smooth photographs gracefully, but text and sharp edges in screenshots reveal compression artefacts at lower qualities.
  • Animated GIFs cannot be converted to single-frame formats here without losing animation. Use the GIF to MP4 tool instead — output is 80% to 95% smaller and preserves motion.
  • If the destination is unknown (an email recipient, a generic CMS), JPEG remains the safest bet. WebP is 'modern' but not yet universal in legacy software like Microsoft Outlook 2016.
