Frequently Asked Questions

Yes. The ASLI FORM Watermark Image Tool is 100% free forever — no registration, no usage limits, no ads and we never add our own watermark to your images.
Yes. Upload multiple images or an entire ZIP archive, design one watermark, and apply it to every image. Then download all results as a single ZIP file.
No. All processing happens 100% inside your browser using the HTML5 Canvas API. Your images never leave your device, which makes the tool safe for client work and private photos.
Yes. Switch to the Logo tab, upload a PNG or SVG (transparent PNG works best), and control its size, opacity, position, rotation, tiling and blend mode.
You can export as PNG (lossless), JPG (smaller) or WEBP (modern), with an adjustable quality setting and an optional resize down to a maximum side length.
Yes. Enable Tile / Repeat to repeat your text or logo diagonally across the entire image with an adjustable gap. Tiling is the strongest protection because the watermark cannot be removed by cropping.
The tool accepts JPG, PNG, WEBP, BMP, GIF and AVIF images, plus ZIP archives containing any of these formats.
The watermark is drawn at the image's full resolution. If you export as PNG the result is lossless; JPG and WEBP use the quality level you choose, so you stay in full control of the final quality.
Yes. The interface is fully responsive and touch-friendly, working on small keypad phones, smartphones, tablets, laptops and desktops. You can upload from your gallery, files app or cloud storage.
There is no hard limit on the number of images. Very large batches are processed one at a time to keep your browser smooth. For best performance on low-end phones, process a few hundred images per batch.
Unlike paid desktop apps or upload-based sites, our tool is free, requires no account, and never uploads your files. You get batch processing, tiling, blend modes and format conversion with complete privacy.
