Best Free Image Converters Compared

An honest comparison to help you pick the right tool for the job.

There are dozens of online image converters, and they all claim to be the best. Here's an honest comparison of eight popular options in 2026, including what each does well and where it falls short. We built My File Tool, so we're biased — but we've tried to be fair, and we'll tell you when a competitor is the better choice.

What to look for in an image converter

  • Format support: Does it handle the formats you actually need? HEIC from iPhones, AVIF for modern web, PSD from Photoshop?
  • Privacy: Does the site track you with ad networks? Does it require an account?
  • Pricing: Is the free tier genuinely useful, or is it a funnel to a subscription?
  • Speed: Does it process files quickly, or queue you behind paying customers?
  • Batch processing: Can you convert multiple files at once, and at what cost?

Which tool is best for you?

  • TinyPNG: Best for simple PNG/JPEG compression if you don't need format conversion.
  • iLoveIMG: Best if you need image editing tools (crop, resize, add text) and don't mind ads.
  • Convertio: Best for video, audio, and document conversion. Overkill for just images.
  • CloudConvert: Best for developers who need an API and support for 200+ file types.
  • Squoosh: Best for single-image optimization with fine-tuned control. Built by the Google Chrome team, runs entirely in your browser. Can't do batch or format conversion beyond 4 formats.
  • Zamzar: Decent all-rounder but slow processing and expensive paid plans ($18-49/month). Best avoided unless you need obscure legacy formats.
  • FreeConvert: Similar to Convertio with aggressive ads. Free tier is limited to 5 files and 1GB. Paid plans run $10-25/month.
  • My File Tool: Best for image conversion and compression with uncommon format support (HEIC, AVIF, PSD, RAW, ICO), no ads, and no subscription.

Bottom line

  • If you only need to compress PNGs, TinyPNG is hard to beat.
  • If you want maximum control over a single image's compression, Squoosh gives you side-by-side previews and format comparison — but it can't do batch.
  • If you need video or document conversion, Convertio or CloudConvert are your options.
  • If you want clean, fast image conversion without ads, accounts, or subscriptions, try My File Tool.

Which converter is best for HEIC/iPhone photos?

Squoosh processes everything locally in your browser — nothing leaves your device. My File Tool and CloudConvert are both ad-free with minimal tracking. iLoveIMG and FreeConvert run heavy ad networks. Convertio uses third-party analytics.
