PNG to WebP Without Squoosh or TinyPNG — Free Alternative With No Limits

Squoosh (by Google) is great for comparing compression quality side-by-side, but it only processes one image at a time. TinyPNG caps free users at 20 images per day. CloudConvert gives you 25 free conversions. Every popular converter has a limitation that shows up right when you need it most.

The WildandFree converter handles unlimited PNG to WebP conversion with adjustable quality, batch processing, and zero file upload. Here is how the options compare.

Squoosh — Best for Quality Comparison, Bad for Batch

Squoosh (squoosh.app, maintained by Google Chrome Labs) is the gold standard for visual quality comparison. Its side-by-side slider shows you exactly what compression does to your image. All processing is local — no server upload.

What Squoosh does well:

• Side-by-side quality comparison at any zoom level
• Supports many formats (WebP, AVIF, JPG, PNG, JPEG XL)
• Fine-grained control over encoding options
• 100% browser-based — no upload

The problem: One file at a time. No batch mode. If you need to convert 20 PNGs to WebP, you are opening and saving each one individually. For a single important image where quality comparison matters, Squoosh is excellent. For everything else, it is too slow.

TinyPNG, CloudConvert, Convertio — The Daily Limit Problem

Tool	Free Limit	Uploads Files?	Quality Control	Paid Plan
TinyPNG	20 images/day	Yes	No (auto)	$25/year
CloudConvert	25/day	Yes	Limited	$8/month
Convertio	100MB/day	Yes	No	$9.99/month
iLoveIMG	15/day	Yes	No	$4/month
ezgif	No stated limit	Yes	Limited	$7.99/month (ad-free)
WildandFree	Unlimited	No	Slider (0-100)	Free

The pattern: server-based tools upload your files, limit usage, and upsell paid plans. Browser-based tools have no per-conversion server costs, so limits are unnecessary. TinyPNG is well-known for PNG compression, but for format conversion to WebP it is just another capped converter.

What Matters in a PNG to WebP Converter

After testing these tools, the features that actually affect your workflow:

1. Batch support. Converting images one at a time is fine for 3 files. For 30 files, you need batch processing with ZIP download
2. Quality control. Without a slider, you are stuck with whatever compression the tool chooses. Some tools compress aggressively by default, producing worse output than necessary
3. No upload. Browser-based processing is faster (no upload/download wait), more private, and eliminates server-side limits
4. Transparency preservation. All WebP converters should preserve PNG transparency, but some poorly-implemented tools botch the alpha channel at low quality settings

Squoosh is the exception — its one-file-at-a-time limitation is offset by the best quality comparison UI available. Keep it bookmarked for the times when you need to pixel-peep a single critical image. Use a batch-capable tool for everything else.

Quick Guide: Which Tool for Which Situation

• Converting 1 critical image with quality comparison? Use Squoosh. The side-by-side slider is unmatched
• Batch converting 10-200 PNGs? Use WildandFree. Drop all files, set quality, ZIP download
• Automated build pipeline? Use cwebp (Google's CLI tool) or ImageMagick. Scriptable, no GUI needed
• Converting between unusual formats (not just PNG to WebP)? CloudConvert supports 200+ formats. Worth the daily limit if you need exotic conversions
• Already paying for Adobe Creative Cloud? Photoshop can export WebP. You are already paying for it, so use it

Frequently Asked Questions

Is WildandFree better than Squoosh for PNG to WebP?

For batch conversion, yes — Squoosh only handles one file at a time. For quality comparison on a single image, Squoosh is better — it has a side-by-side slider for comparing compression. Use Squoosh for critical single images, WildandFree for batch jobs.

Why does TinyPNG limit free users to 20 images?

TinyPNG processes images on their servers, which costs money per conversion. The free limit pushes users toward the $25/year Pro plan. Browser-based tools have no server costs per conversion, so there is no reason for a limit.

Is there a free PNG to WebP converter with no daily limit?

Yes. Browser-based tools like WildandFree have no daily limits because they process images in your browser, not on a server. Squoosh (Google) is also unlimited but only handles one file at a time.

Does Canva convert PNG to WebP?

Canva can export designs as WebP, but it does not have a dedicated image converter tool. You cannot upload a PNG and download a WebP. For format conversion, use a dedicated converter.
