A TinyPNG-style workflow — with a zero-upload guarantee
TinyPNG and similar tools are great for consumers. B2B teams often need auditable data flows. ConV removes the upload path entirely.
Presets for e-commerce and blogs help you produce consistent outputs quickly.
Same underlying codecs, no API key needed, no file size quota from a third-party plan.
Key benefits
- Same codec quality (MozJPEG, libwebp, libpng) without cloud upload
- No account required, no per-image quotas from TinyPNG
- Batch compress dozens of images at once
- EXIF metadata stripped during re-encode
Common use cases
- Teams who currently use TinyPNG but need zero-upload privacy
- Agencies with data processing agreements restricting cloud tools
- Developers who want TinyPNG compression quality locally
- Teams with high monthly image volumes avoiding TinyPNG API costs
How it works
- 01
Drop JPEG or PNG files (or WebP/AVIF)
- 02
Select quality and output format
- 03
Local WASM codecs compress in parallel
- 04
Download ZIP — no API calls, no upload
Limitations and realistic expectations
ConV does not use TinyPNG's proprietary algorithms. Results are similar but not identical. Evaluate output quality against your requirements.
Frequently asked questions
Does ConV produce the same output as TinyPNG?
ConV uses open-source WASM codecs (MozJPEG, libwebp). Results are comparable but not byte-identical to TinyPNG.
Is ConV free to use?
Yes — ConV has a free tier for up to 20 images per session. ConV Pro unlocks unlimited images and additional features.
Does TinyPNG upload my images?
TinyPNG sends images to their API server. ConV does not — all processing is local in your browser.
Can I use ConV as a TinyPNG replacement for teams?
Yes. ConV offers batch processing and ZIP export suitable for team workflows.

Compress locally instead of sending files to the cloud
Classic online compressors are convenient but not always compliant for sensitive work. ConV keeps originals on your device; outputs are built with WASM encoders right in the tab.
No-upload image optimizer for private workflows
Most image optimizers send your files to a remote server. ConV takes a different approach: the entire compression pipeline runs inside your browser using WebAssembly.
GDPR-friendly image compression without image uploads
Sending employee or client images to a third-party cloud API creates data processing questions. ConV avoids this entirely: the compression pipeline runs in your browser — your images never reach ConV servers.
