Upload an image, pick the target format, adjust quality for lossy formats (JPEG, WebP), and download. For PNG/WebP with transparency, enable the transparent background option. All conversion happens locally via HTML5 Canvas — no uploads.
Supported formats: PNG (lossless, transparency), JPEG (lossy, photos), WebP (modern, smaller), BMP (uncompressed), ICO (favicons), TIFF (print).
Format triage: Photos to JPEG or WebP, graphics to PNG, modern delivery to WebP, print to TIFF. Austin startups shipping $100,000 sites cut hero weights 70 percent switching JPEG to WebP on 09/22/2026.
Transparency rules: PNG and WebP keep alpha with the toggle on; JPEG and BMP flatten to background. Chicago studios delivering $20,000 logo packs verify checkers before handoff.
ICO favicons: Square sources convert cleanest at 16, 32, 48 multi-size. Miami bloggers cutting $2,000 load-time budgets ship one ICO covering all tabs.
Quality dials: JPEG 85 balances crispness and bytes; WebP 80 matches visually smaller. Denver docs publishing $50,000 manuals standardize 85 across figures.
Batch reality: One file per run under a second each — true bulk belongs to Sharp or ImageMagick CLIs.
Startup shipping: Austin teams launching $100,000 marketing sites convert 200 hero JPEGs to WebP, cutting loads from 4 seconds to 1.2 on 09/22/2026.

Frequently Asked Questions
- Does it preserve transparency?
- Yes, for PNG and WebP when "Transparent Background" is checked. JPEG and BMP cannot store transparency.
- Can I convert to ICO for favicons?
- Yes, select ICO format. For best results, use a square image (16×16, 32×32, 48×48).
- Does it support batch conversion?
- Process files one by one — each takes <1s. For true batch, use a CLI tool like Sharp or ImageMagick.
- WebP browser support?
- Universal in modern browsers since 2020. Serve JPEG fallbacks only for legacy enterprise users.
- Quality setting kept?
- Per conversion — the dial resets. Standardize team values in a shared doc.
- TIFF when?
- Print and archival masters. Never serve TIFF on the web — files dwarf equivalents.
