Frequently Asked Questions
Do I need to create an account to use ExifLens?+
No. ExifLens works entirely without sign-up — just open the page and drop in a photo.
Are my photos uploaded to a server?+
No. Every calculation and every pixel of processing happens locally in your browser. Your photos never leave your device.
What image formats does ExifLens support?+
JPG and PNG are fully supported, along with most common camera RAW formats (ARW, CR2, CR3, NEF, RAF, RW2, ORF, DNG, PEF, SRW).
How does the ND filter calculator work?+
Enter your base (unfiltered) shutter speed and pick the ND filter strength you're using — the calculator instantly shows the new shutter speed needed for the same exposure, plus an optional countdown timer for the shot.
Can I customize the frame before downloading?+
Yes. Every theme's colors, font, padding, and brand logo visibility can be adjusted, and you can edit any of the text fields shown on the frame without changing the EXIF data itself.
Is ExifLens free to use?+
Yes, completely free. The site is supported by ads and occasional affiliate links, which never affect how the tools themselves work.
