Top Recommended Replacements
CloudConvert
FREETop Professional Alternative
Why we like it
Extremely generous free tier (25 conversions/day); superior interface; supports Google Drive/Dropbox integration; allows for fine-tuning of conversion settings (bitrate, resolution).
Keep in mind
Credits for high-volume use can become expensive; some specialized CAD/3D formats are better handled by Zamzar.
FreeConvert
FREEBest for Large Files
Why we like it
Massive 1GB file limit on the free tier; supports batch processing; includes basic editing tools (resize, crop, compress); very fast upload/download speeds.
Keep in mind
The free site is heavy on advertisements; the 'Pro' features are locked behind a subscription.
FileZigZag
FREEBest No-Registration Alternative
Why we like it
Clean, simple interface; no account required for basic use; uses high-end CPUs for rapid processing; supports a vast array of document and image formats.
Keep in mind
Daily limits are lower than CloudConvert; file size limit for free users is typically around 50MB-150MB.
Convertio
FREEBest UI/UX Experience
Why we like it
Most modern and intuitive interface; excellent browser extension; supports 25,000+ different conversions; advanced OCR (Optical Character Recognition) for PDFs.
Keep in mind
Free file size limit is strictly 100MB; concurrent conversions are limited on the free tier.
