About image formats
Quick reference for the formats DoItSwift tools handle most often.
HEIC / HEIF
Apple’s default photo format on iPhone and iPad. It saves space with modern compression. Many desktops need a conversion to JPG or PNG for editing or sharing — our HEIC to JPG tool does that locally in your browser.
WEBP
Google’s web-optimized format: strong compression with transparency support. Not every older app opens WebP; converting to JPG is a common step when you need maximum compatibility.
AVIF
A next-generation format with excellent size-to-quality ratio. Support is growing; when you need a JPG for a legacy workflow, use AVIF to JPG — decoding happens with your browser’s native AVIF support.
PNG
Lossless raster images with transparency. Great for UI assets and graphics. PNG files are often larger than JPG; compressing or converting to JPG can shrink photos when transparency is not needed.
JPG / JPEG
The universal photo format for web and print previews. Lossy compression; ideal for photographs and any situation where a smaller file matters and slight quality loss is acceptable.
SVG
Scalable vector graphics: crisp at any size, ideal for logos and icons. Browsers render SVG as XML; when you need a raster PNG for a legacy app or fixed pixel dimensions, use our SVG to PNG tool — export stays on your device.

Image tools FAQ
Which format should I use for my website?
For photos, modern sites often serve WebP or AVIF with a JPG fallback. For logos with transparency, PNG or SVG is typical. Use our compress and resize tools to keep file sizes small without visible quality loss. For a deeper comparison, read best image format for websites.
Are my images uploaded to DoItSwift?
No. These tools run in your browser; your files stay on your device unless you explicitly use a future feature that says otherwise. Disconnect from the internet after the page loads and conversions still work.
Will converting reduce quality?
JPG and lossy compression always trade size for quality. Use higher quality settings when you need crisp output; use stronger compression for thumbnails and social previews.
Can I process many files at once?
Yes. Most tools support batch selection or drag-and-drop of multiple files, with ZIP download where it makes sense. There are no artificial batch limits.
Do these tools work on mobile?
Yes. Use Safari on iPhone, Chrome on Android, or any modern mobile browser. Very large files may be slower on older phones.
