What's the difference between ICO and JPG?

ICO is the Windows icon format and the classic home of the site favicon.ico. JPG (also written JPEG) is the workhorse lossy format for photographs.

Will I lose quality converting from ICO to JPG?

Yes — JPG discards some image detail in exchange for much smaller files. At quality 80 or above the difference is usually invisible to the eye. For maximum quality, use quality 90+. For maximum compression, drop to quality 70 (still acceptable for most photos).

What quality should I pick?

For JPG, quality 75-85 is the sweet spot — small files with no visible difference from the original. Lower than 60 starts to show artifacts. Higher than 90 mostly just makes the file bigger.

When is JPG the right format?

JPG is a good choice for: photographs, especially anything with smooth gradients (sky, skin, water); social media uploads where size matters more than perfect fidelity; email attachments and chat where compatibility is paramount. It is a poor choice when anything that needs transparency (use PNG or WebP).

Anything surprising about ICO or JPG?

Modern .ico files embed PNG frames; convert.now packs a single PNG frame per icon. And on the JPG side: JPG quality 80–85 is usually visually indistinguishable from the original. Don't ship q100.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and conversions run on-device just like desktop. Large files may be slower on mobile due to CPU and memory constraints, but the workflow is identical.

What's the maximum file size?

No hard limit — the browser handles it. Files under 50MB convert in a few seconds. Larger files work but may take longer as the browser allocates memory. If you hit issues, batch in smaller groups.
