Question 1

What image formats can I upload?

Accepted Answer

HEIC/HEIF, SVG, PNG, JPEG, WebP, BMP, GIF, AVIF, and TIFF. Output formats are PNG, JPEG, WebP, and SVG (bitmap tracing). SVG input can be exported to any raster format; raster images can be traced to SVG.

Question 2

What is the best format for web images?

Accepted Answer

WebP is generally the best format for web — it provides smaller file sizes than JPEG and PNG at similar quality, supports transparency (like PNG), and is supported by all modern browsers. AVIF is even more efficient but has slower encoding and less universal browser support. PNG is best for screenshots, diagrams, and images with text.

Question 3

When should I use SVG vs PNG?

Accepted Answer

SVG (Scalable Vector Graphics) is ideal for logos, icons, illustrations, and anything with flat colour and geometric shapes — it scales without pixelation. PNG is better for photographs, complex gradients, and screenshots. SVG files can be very small for simple shapes; PNG can be smaller for complex photographic content.

Question 4

Can I convert HEIC photos from my iPhone?

Accepted Answer

Yes. Upload .heic or .heif files from an iPhone or other Apple device and convert them to PNG, JPEG, WebP, or SVG. HEIC is decoded in your browser — nothing is uploaded to a server.

Question 5

Can I convert a PNG to SVG?

Accepted Answer

Yes. Choose SVG as the output format and the tool traces the bitmap into vector paths. This works best for logos, icons, and flat graphics with few colours. Photographs and complex gradients produce large SVGs with many paths — for those, PNG or WebP is usually a better choice.

Question 6

Is my image safe here?

Accepted Answer

Yes. Conversion runs in your browser. Your image is never uploaded to a server.

Question 7

What quality level should I choose?

Accepted Answer

For web images: 70–80% quality typically provides a good balance between visual quality and file size. JPEG at 80% is usually indistinguishable from 100% for most photos. For images with text or sharp lines, use higher quality (85–90%) as JPEG compression artefacts are more visible on edges.

Question 8

Will I lose quality every time I compress?

Accepted Answer

Yes. JPEG is a lossy format — each compression introduces artefacts. Never compress an already-compressed JPEG for distribution; always start from the original uncompressed source. Keep a TIFF or PNG master and compress from that for each use.
