Frequently Asked Questions

No. Every conversion on IMGVO runs entirely in your browser using JavaScript. Your images are never sent to any server. They stay on your device from start to finish. This is why there are no file size limits and no waiting for uploads.
For photos: use AVIF as your primary format — it's typically 40–55% smaller than JPG at the same quality. Add a WebP fallback for any browser that doesn't yet support AVIF. For logos and icons with transparency: use WebP lossless or PNG. For maximum compatibility with no trade-offs: JPEG and PNG still work everywhere.
You control the quality. IMGVO provides a quality slider (1–100) before you convert. At 80–85 quality, WebP and AVIF are visually indistinguishable from the original JPEG — while being significantly smaller. At 100, lossless mode preserves every pixel exactly.
Lossy compression discards some image data to achieve a smaller file size. JPEG is always lossy; WebP and AVIF support both modes. Lossless compression keeps every pixel bit-for-bit identical to the original. PNG is always lossless. Use lossless when you need to edit the image again later, or when it contains legible text. Use lossy for photos and final web delivery.
Yes. All IMGVO converters support batch processing — drag in multiple files at once and they will all be converted and downloaded as a ZIP. The number of files you can process at once is limited only by your device's memory.

Which Image Format Should You Use in 2026?

Images are typically the largest assets on any webpage — often accounting for 50–70% of total page weight. Choosing the right format and converting correctly can cut that weight in half, directly improving Core Web Vitals, load times, and search rankings.

AVIF: the 2026 standard for photos

AVIF (AV1 Image File Format) is now supported by all major browsers and delivers the highest compression efficiency available. At equivalent visual quality, AVIF files are typically 40–55% smaller than JPEGs and 20–30% smaller than WebP. Use our JPG to AVIF or PNG to AVIF converters to upgrade your image library.

WebP: the safe universal choice

WebP is supported by all modern browsers and offers around 25–35% smaller file sizes than JPEG with comparable quality. Unlike JPEG, WebP supports both lossy and lossless compression as well as transparency — making it a single format solution for both photos and logos. Convert any image to WebP with our JPG to WebP or PNG to WebP tools.

PNG: when lossless matters

PNG produces perfect copies with no quality loss, making it the right choice for screenshots, images with text, diagrams, and anything you plan to edit further. If file size is a concern, convert PNG to lossless WebP for up to 25% savings with zero quality difference.

JPG: legacy compatibility

JPEG remains useful when you need guaranteed compatibility with older systems, email clients, or software that doesn't support modern formats. It also has strong hardware decoding support on mobile devices, which can be relevant for very large photo libraries.

The quick decision rule

  • Photo for web → AVIF (WebP fallback)
  • Logo or icon with transparency → WebP lossless (PNG fallback)
  • Screenshot or text image → PNG
  • Maximum compatibility → JPEG or PNG
  • Document workflow → PDF
