Question 1

Does the HEIC to JPG converter work on Windows, or only on Mac?

Accepted Answer

It works on any operating system — Windows, Mac, Linux, Android, iOS. The conversion runs in your browser using the heic2any library (WebAssembly-based), so there is no operating system dependency. The only requirement is a modern browser (Chrome 88+, Firefox 85+, Safari 14+). HEIC files from iPhones can be converted on any device.

Question 2

Why does my JPEG sometimes get larger after removing EXIF data?

Accepted Answer

EXIF removal forces a re-encode of the JPEG through the Canvas API, which can produce a larger file if the original was compressed with a superior encoder like Adobe Lightroom or Google's Guetzli. Our EXIF remover uses binary-search quality reduction to ensure the output never exceeds the input file size — it will lower JPEG quality incrementally until the size matches.

Question 3

Can I batch convert or resize multiple images at once?

Accepted Answer

The Bulk Image Resizer (coming soon) handles up to 20 images at once and downloads them as a ZIP. The HEIC converter also accepts multiple files. For the current single-file tools, process files one at a time. Bulk processing on the client side runs sequentially — not in parallel — to avoid blocking the browser UI on older phones.

Question 4

Is the Base64 output safe to use directly in an HTML img src tag?

Accepted Answer

Yes. The output format is a standard data URL: data:image/jpeg;base64,... — paste it directly into the src attribute of an img tag or into a CSS background-image. Be aware that Base64 increases file size by roughly 33% compared to the binary file, so it is best for small images like icons and avatars, not large photos.

Question 5

What is the difference between WebP and JPG, and when should I use WebP?

Accepted Answer

WebP typically produces files 25–35% smaller than JPEG at equivalent visual quality. Use WebP for web images where you control the HTML — blog thumbnails, product images, OG images. Use JPG when submitting to external systems (government portals, social media upload forms) that specify JPG or do not accept WebP. All modern browsers support WebP.

Format	Best for	Transparency	Typical size vs JPG
JPG / JPEG	Photos, government forms	No	Baseline
PNG	Screenshots, logos, UI	Yes	2–5× larger
WebP	Web images, thumbnails	Yes	25–35% smaller
HEIC	iPhone photos (storage)	No	40–50% smaller than JPG
SVG	Icons, logos (vector)	Yes	Scales to any size
ICO / Favicon	Browser tab icons	Yes	Multi-size container
