How it works

  1. 1 · Drop your files

    Drag & drop or choose WebP files. No account required—paid plans unlock bigger batches, higher limits, and priority queues.

  2. 2 · We convert securely

    Processed on our dedicated servers. Encrypted in transit & at rest. Metadata stripped by default. We never store filenames—only file types & sizes for accounting. We never train AI models on uploads.

  3. 3 · Download & auto-delete

    Grab your PNGs in seconds. Files delete automatically after 1 hour. Delete anytime after downloading with one click.

WebP is Google's modern image format offering both lossy and lossless compression modes, plus alpha transparency and animation support—essentially combining the best features of JPEG, PNG, and GIF. Announced in 2010, WebP typically delivers 25-35% smaller files than JPEG at comparable quality using VP8 or VP8L compression. All major browsers now support WebP, making it a practical choice for web optimization.

WebP strikes an excellent balance between compression efficiency and ecosystem maturity. It's widely adopted for web delivery, supported across all modern browsers (Chrome 32+, Firefox 65+, Safari 14+, Edge 18+), and offers better compression than JPEG/PNG without the encoding overhead of AVIF.

CMS support: WordPress 5.8+ (July 2021) supports WebP natively. Most modern CMS platforms and CDNs (Cloudflare, Akamai, Fastly) can automatically serve WebP to compatible browsers via content negotiation.

Email limitation: Most email clients (Outlook, Gmail web, Apple Mail) do not support WebP. Always use JPG or PNG for email images, or provide a JPG fallback via <picture> elements in HTML emails.

PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.

Frequently Asked Questions

Why convert WebP back to PNG? Isn't WebP better?

WebP is excellent for web delivery (25-35% smaller than JPEG, 93% browser support), but PNG offers unique advantages for specific workflows:

  • Universal compatibility: PNG works on 100% of devices, browsers, and software (vs WebP's 93% browser support, lower desktop app support)
  • Editing workflows: Photoshop, GIMP, and design tools prefer PNG as the standard lossless format
  • Archival stability: PNG has been stable for 25+ years; WebP is newer (2010) and still evolving
  • Transparency standard: PNG is the established format for transparent graphics, logos, and UI assets
  • Legacy software: Pre-2020 desktop apps often don't support WebP natively

When to choose PNG: Editing, archiving, legacy systems, print workflows, universal compatibility.
When to keep WebP: Modern web delivery, file size critical, browsers/apps known to support it.

Will my file size increase?

Yes, moderately. PNG files are typically 2-4× larger than WebP (range: 2-5×). This is expected and unavoidable:

  • 500 KB WebP → 1-2 MB PNG
  • 1 MB WebP → 2-4 MB PNG
  • 2 MB WebP → 4-8 MB PNG

Why such a big difference? WebP uses modern VP8/VP9 compression optimized for photos. PNG uses lossless DEFLATE compression from 1996 that wasn't designed for photographic content. You're trading file size for perfect lossless quality and universal compatibility. Need universal compatibility without the file size bloat? Try WebP to JPG for 100% browser support with much smaller files.

Will I lose quality?

No! WebP to PNG conversion is completely lossless. The WebP is decoded perfectly (every pixel, every color value), and PNG encodes every pixel exactly as decoded with zero compression artifacts.

What's preserved:

  • Pixel-perfect accuracy (100% lossless)
  • Transparency/alpha channel (if present in WebP)
  • Color depth (decoded to full RGB or RGBA)

What's NOT preserved:

  • EXIF metadata (stripped by default for privacy, configurable)
  • File size efficiency (PNG is 2-4× larger)

What happens to transparency?

PNG fully supports alpha channels (transparency). Any transparency in your WebP will be perfectly preserved in the PNG output.

  • WebP with alpha → PNG with alpha (default behavior)
  • WebP without alpha → PNG without alpha (RGB only, smaller file)

This is one of PNG's strengths compared to JPG (which doesn't support transparency). Both WebP and PNG support transparency, so conversion is lossless.

What happens to animated WebP files?

We extract the first frame. Animated WebP (like animated GIF) can't be represented in static PNG format. We convert the opening frame to a lossless PNG.

Need to preserve animation?

  • Keep as WebP: If your target supports it (97% of browsers)
  • Convert to GIF: Universal compatibility but larger files and 256-color limit

Both animated and static WebP files are accepted—animation is simply not preserved in the static PNG output.

How fast is WebP decode?

Fast. WebP uses the VP8/VP9 codec, which is optimized for quick decode times while maintaining good compression. Expect conversion times similar to JPEG→PNG.

Typical times (based on 10MP image):

  • WebP→PNG: 200-400ms (fast, VP8/VP9 codec)
  • HEIC→PNG: 300-600ms (moderate, HEVC codec)
  • AVIF→PNG: 600-1200ms (slow, AV1 codec)

Why? WebP's VP8/VP9 codec is designed for real-time video streaming, so decode is fast. PNG encoding adds minimal overhead (~50-100ms).

How are credits calculated for this conversion?

Cost: 1 credit each

How it works:

  • Files up to 25 MB: 1 credit (minimum)
  • 26-50 MB: 2 credits
  • 51-75 MB: 3 credits
  • 76-100 MB: 4 credits
  • Over 1000 MB: 40 credits (maximum cap)

Example: A 5 MB image = 1 credit. A 95 MB image = 4 credits.

Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).

What are my daily and monthly credit limits?

Credit allocations vary by account tier:

TierDaily LimitMonthly Limit
Free50 credits/day
Pro10,000 credits/month
Business30,000 credits/month

Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.

Note: With 1 credit each, images under 25 MB cost 1 credit each. Pro users can convert 10,000 images per month.
