Watermark all your photos at once — right in your browser

Watermarking a whole shoot, not one photo at a time

Watermarking is rarely a single-image job. It comes up when you are posting a gallery, sending proofs to a client, or listing a batch of products — dozens of files that all need the same mark in the same place. Doing that in an image editor means repeating yourself; doing it on an upload-based site means handing over the entire set.

MarkFit applies your mark to the whole batch in one pass, inside the browser. Set it up once against a live preview, then export the finished images as a ZIP. The photos are read from your disk and written back as downloads without ever being transmitted.

Text, logos and placement

• Text watermarks — a studio name, a copyright line, or a client's proof label.
• Logo watermarks — drop in your own image file with transparency preserved.
• Anchor placement — pin the mark to a corner or the centre, applied consistently across every photo.
• Tiling — repeat the mark across the whole frame, which is much harder to crop out of a proof.

Photos keep their original dimensions, and EXIF orientation is applied automatically, so sideways phone shots come out the right way up.

Frequently asked questions

How many photos can I do at once?

Batches of up to five are free. A one-time purchase removes the limit and adds tiled watermarks and saved templates for marks you reuse.

Does watermarking reduce image quality?

Dimensions are preserved and output is high-quality JPEG — or PNG, if you put a PNG in.

Are my photos uploaded?

No. Everything runs on your own device, so client work and unreleased shots never leave it.
