Is this SVG to AVIF converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple SVG files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

At what resolution is the SVG rasterised to AVIF?

The SVG is rendered at 2× screen resolution (2x retina) by default, producing sharp output on high-DPI displays. For larger output, scale the SVG before converting.

Should I use AVIF or PNG for rasterising an SVG for the web?

AVIF if you want the smallest file size and good browser support; PNG if you need lossless pixel-perfect output or broader legacy browser compatibility. For simple logos, PNG's lossless nature often preserves sharp edges better.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert SVG to AVIF?

SVG is a vector format — it scales infinitely without losing quality, which makes it ideal for logos, icons, and UI graphics. But SVG is also a text-based format that browsers render dynamically, and many platforms don't accept SVG uploads at all. Product image fields in e-commerce platforms, social media, email clients, and CMS media libraries typically require raster formats.

Converting SVG to AVIF rasterizes the vector at a fixed resolution and then encodes it with AVIF's highly efficient compression. The result is a file that's accepted anywhere images are displayed, while still being very small. For sharp-edged graphics like logos and icons, AVIF's encoder handles the crisp lines and flat colors well, and the file sizes are tiny — often under 50 KB for icon-scale artwork. AVIF is supported in all modern browsers and is increasingly the preferred delivery format for web images due to its efficiency.

The key decision is rasterization resolution. When converting SVG to any raster format, you choose the output pixel dimensions — and unlike the SVG source, you can't scale up afterward without losing sharpness. Choose a resolution appropriate for the largest size you'll display: 512×512 for general web use, 1200×1200 for social media, or higher for print. For AVIF web delivery, 800×800 or 1000×1000 is usually more than sufficient, and even at those sizes the files remain small.

Quality & file size: SVG to AVIF

Typical file sizes: SVG 5–50 KB → AVIF 0.8–2 MB.

Both SVG and AVIF use lossy compression. We transcode at high quality settings (equivalent to AVIF's recommended web quality) to minimize generational loss.

Color depth: SVG supports unlimited (vector), AVIF supports 12-bit.

Transparency: SVG supports transparency. AVIF preserves transparency.

Privacy: how FormatDrop handles your files

Your SVGfiles are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
