Question 1

Which image formats can I convert between?

Accepted Answer

You can convert to JPEG, WebP, PNG, and AVIF. Source files can be JPEG, PNG, WebP, AVIF, or GIF. This covers the vast majority of images you will encounter, whether from a camera, a screenshot, or a design tool.

Question 2

Are images uploaded during conversion?

Accepted Answer

No. Conversion runs entirely in your browser using built-in encoders. Nothing is sent to a server, so it is safe for private photos and you do not need to wait in any upload or processing queue.

Question 3

When should I use AVIF or WebP?

Accepted Answer

AVIF and WebP offer the best compression for photos on the web, often 30-50% smaller than JPEG at the same quality. Use them for websites, apps, and online stores where faster loading matters. Most modern browsers support both.

Question 4

When should I use PNG?

Accepted Answer

PNG is lossless and supports transparency, making it ideal for graphics, logos, icons, and screenshots with sharp edges or text. The trade-off is that PNG photos are much larger than JPEG or WebP, so use it mainly for non-photographic content.

Question 5

When should I use JPEG?

Accepted Answer

JPEG is the most universally compatible format and works in every app and browser. Use it for photographs when you need maximum compatibility and do not need transparency. It does not support transparency and uses lossy compression.

Question 6

Why is the quality slider disabled for PNG?

Accepted Answer

PNG is a lossless format, so there is no quality trade-off to adjust - the output is always pixel-perfect. The slider only affects JPEG, WebP, and AVIF, which are lossy and let you balance size against visual quality.

Question 7

Can I convert multiple images at once?

Accepted Answer

Yes. Select or drop multiple files and they are converted one after another. You can download each file individually, or grab them all as a single ZIP archive - handy when prepping a batch for a website or delivery.

Question 8

Does converting reduce file size?

Accepted Answer

It depends on the target format and quality. Converting a PNG photo to WebP or AVIF usually shrinks it a lot, while converting a photo to PNG may actually increase the size. Lowering the quality also reduces size for lossy formats.

Question 9

Is there a file size or count limit?

Accepted Answer

There is no hard limit, but very large batches are constrained by your device memory since everything runs locally in the browser. For hundreds of large photos, convert in smaller groups to keep things smooth.

Question 10

Does conversion preserve EXIF metadata?

Accepted Answer

No. Re-encoding does not carry over EXIF data, so converted files will not contain the original camera settings or GPS. This is good for privacy when sharing - your location and device info do not leak with the image.
