Frequently asked questions
Is PixelTools image converter free?
+
Yes, completely free with no limits. Convert as many images as you want, as often as you want. No subscription, no trial, no account required.
What image formats can I convert between?
+
PixelTools supports 8 input formats (JPG, PNG, WebP, HEIC, BMP, TIFF, SVG, AVIF) and 3 output formats (JPG, PNG, WebP). This covers all common conversion needs including iPhone HEIC photos and next-gen formats.
Are my images uploaded to a server?
+
No. PixelTools converts images entirely in your browser using the Canvas API and WebAssembly. Your files never leave your device — there is no server upload, no cloud processing, and no data stored anywhere.
Can I convert HEIC photos from my iPhone?
+
Yes. PixelTools includes a built-in HEIC decoder (via WebAssembly) that runs locally in your browser. Drop your HEIC photos and convert them to JPG, PNG, or WebP instantly.
Can I convert multiple images at once?
+
Yes. Drop or select as many images as you need — they are all converted in batch. You can download each file individually or all at once as a ZIP file.
Does converting images reduce quality?
+
It depends on the output format. Converting to PNG is lossless — zero quality loss. Converting to JPG or WebP uses lossy compression, but at the default settings the difference is imperceptible.
How is this different from Convertio or iLoveIMG?
+
Those tools upload your images to their servers for processing and impose daily limits on free accounts. PixelTools converts everything locally in your browser with no upload, no limits, and no account required.
What is the maximum file size I can convert?
+
PixelTools can handle images up to 100 MB each. Very large images or HEIC files may take a few seconds to process depending on your device.
