Convert image FAQ

How do I convert an image to a different format?
Drop your image files onto the upload area (or click Choose files), select the output format from the 'To' selector, adjust the quality slider if needed, then click Convert. Download individual files or use Download all to save everything as a ZIP.
Can I convert HEIC photos from iPhone?
Yes. Drop your HEIC or HEIF files directly onto the tool and choose an output format like JPG or PNG. The conversion happens entirely in your browser — no app or plugin required.
What is the difference between JPG, PNG, WebP, and AVIF?
JPG is great for photos (small file, lossy). PNG is best for graphics and transparency (lossless). WebP offers better compression than JPG at similar quality. AVIF is the newest standard with the best compression, supported by all modern browsers.
Is there a limit on how many images I can convert?
There is no enforced limit. You can drop as many files as you like; they are all processed locally in parallel. Very large batches may be constrained by your device's available memory.
Does converting to WebP or AVIF reduce quality?
Both WebP and AVIF are lossy by default, but at a quality setting of 80 or above the difference from the original is usually imperceptible. Use the quality slider to find the best trade-off for your use case.
