How It Works
FileZoom decodes your image directly in the browser — using the browser's built-in codecs, supplemented by JavaScript decoders for formats like HEIC — then draws it onto an in-memory canvas and re-encodes it into the format you selected. Because decoding and encoding both happen on your device, conversion works without any server and your original file is never modified or uploaded.
Tips & Best Practices
- Converting iPhone photos? Choose JPG for maximum compatibility, or WebP/AVIF for the smallest files.
- Going to JPEG from a transparent PNG turns transparent areas white — keep PNG or WebP if you need transparency.
- For modern websites, AVIF gives the smallest files; fall back to WebP or JPG for older software.
- Need many files in one format? Batch Convert turns up to 50 images into a single target format at once.
FAQ
When should I use PNG vs JPEG vs WebP?
Use PNG for images with transparency or sharp edges. Use JPEG for photos. Use WebP for smaller file sizes on modern websites.
Will converting to JPEG remove transparency?
Yes. JPEG does not support transparency. Transparent areas will be filled with a white background.
Are my images uploaded to a server?
No. Conversion uses the Canvas API entirely in your browser.
Does converting affect image quality?
Converting to a lossy format like JPEG may slightly reduce quality. Converting to PNG is lossless.
How do I convert HEIC photos from an iPhone?
Just drop the HEIC file in and choose JPG or PNG as the output. The HEIC decoder runs in your browser, so it works on Windows and Android too.
What is AVIF, and when should I use it?
AVIF is a modern format with even smaller files than WebP at similar quality. Use it for websites; for maximum compatibility with older software, JPG or PNG is safer.
Can I convert many images at once?
For bulk conversion, use FileZoom's Batch Convert tool — it converts up to 50 images to one target format in a single run.
Does converting change the image dimensions?
No. Width and height stay the same; only the encoding format changes. Use the Resize tool if you also need different dimensions.
