When should I use WebP instead of JPEG?

WebP is the best choice for web images — 25–35% smaller than JPEG at equivalent quality, supported by all modern browsers since 2021. Use JPEG when sharing with people who may open files in older software.

Will converting lose image quality?

Converting to JPEG or WebP (lossy) at high quality (85–95%) has minimal perceptible quality loss. Converting PNG to PNG is lossless. Converting JPEG to PNG does not recover lost quality but produces a lossless file.

Does converting strip EXIF metadata?

Yes — the Canvas API redraws the image pixel-by-pixel, stripping all EXIF metadata. Use the Strip EXIF tool explicitly if you want to control this process.

Can I convert HEIC (iPhone photos)?

HEIC conversion is handled by the dedicated HEIC to JPG tool, which uses the heic2any library for reliable decoding across all browsers.

Why is my PNG output larger than the JPEG?

PNG is a lossless format — it stores all pixel data without compression artefacts. For photos, JPEG or WebP will always produce smaller files. PNG is best for images with text, logos, or transparency where quality is critical.

Format guide — when to use JPEG, PNG or WebP

Choosing the right image format has a significant impact on file size, quality, and compatibility. Here is a practical guide:

JPEG — photos and real-world images

Best for: photographs, product images, real estate photos, social media. Lossy compression produces very small files. Use 85–95% quality for web images, 95–100% for editing or print. Supported everywhere.

PNG — logos, text and transparency

Best for: logos, icons, screenshots, images with transparent backgrounds, diagrams with text. Lossless — no quality loss at any setting. Significantly larger than JPEG for photographs.

WebP — web-first modern format

Best for: any web image where file size matters. Supported by all browsers since 2021. Produces files 25–35% smaller than JPEG and 26% smaller than PNG at equivalent quality. Ideal for e-commerce, blogs, and web apps.

Format comparison by use case

Use case	Recommended format	Reason
Instagram / social media post	JPEG or WebP	Platform recompresses anyway; start with high quality
Amazon product main image	JPEG	Amazon requires JPEG for main images
Shopify / WooCommerce product	WebP	Fastest loading; Shopify auto-converts to WebP anyway
Website hero / banner	WebP	Best balance of quality and file size for web LCP
Logo with transparent background	PNG	Only format that preserves true transparency (besides WebP)
Background-removed product image	PNG or WebP	Preserves transparency for layering in design tools
Screenshot / diagram with text	PNG	Lossless prevents blurry text compression artefacts
Email newsletter image	JPEG	Maximum compatibility with email clients
Canva / Figma import	PNG or WebP	Supports transparency; no JPEG artefacts on graphics

Frequently asked questions

What is WebP and should I use it? ▼

WebP is a modern image format developed by Google that produces files 25–35% smaller than JPEG at equivalent visual quality. It is supported by all major browsers since 2021 (Chrome, Firefox, Safari, Edge). For web use, WebP is almost always the best choice. For sharing with users who may open files in older software like Windows Photo Viewer (pre-2019), JPEG is safer.

Will converting JPEG to PNG improve quality? ▼

No. JPEG is a lossy format — converting to PNG creates a lossless copy of an already-compressed image. You get a larger file with no quality improvement. The only reason to convert JPEG to PNG is when you need a lossless format for further editing or when transparency is required.

Can I convert multiple images at once? ▼

Batch conversion is coming in V2. Currently each image is converted individually.

What quality setting should I use? ▼

For web images: 85–90% for JPEG and WebP gives the best size-to-quality ratio. For archiving or print: 95–100%. For thumbnails where file size is critical: 75–80%.
