• How do I stamp my WhatsApp number on product photos before sending them to customers?Type the number as the watermark text, bold with an outline and big enough to read on a phone, and watch where the + goes if the line starts with Arabic.
• Can I put my shop's QR code on a product photo as a watermark?Yes: make a PNG QR code and upload it as the logo, then set opacity to 100%, rotation to 0 and a size big enough to scan, and test the download with your phone.
• If I want my watermark in my brand's font, should I use the text option or a logo image?The text option draws only IBM Plex, on one line. For your brand typeface, two lines or several colors, export your name as a transparent PNG and upload it as the logo.
• I have 80 product photos; how do I give all of them the exact same watermark?The tool takes 30 images at a time, so split 80 photos into three rounds with the same settings. Settings survive between rounds, and file names do not clash.
• How do I send a client a preview of my design without them using it before paying?Send a smaller copy with a repeated mark across the whole design at moderate opacity, and keep the full file until payment. Repeated mark versus corner mark.
• Why did my watermarked image come out as a heavy PNG, and how do I get a JPG instead?The watermark tool always keeps the input format, and PNG is saved lossless, which is heavy for photos. Convert to JPEG after watermarking, not before.
• How do I straighten a product photo that is tilted by two degrees without ending up with empty corners?Type a small angle such as -2 or 1.5 in the angle field. Any free-angle turn leaves small empty corners, and the way to lose them is to crop the edges afterwards.
• Why is the writing on my product backwards in a photo I took with the front camera?Some phones save front camera photos mirrored, so text and logos read backwards. Rotating cannot fix that; a horizontal flip does it in a second.
• Does a JPEG lose quality if I rotate and save it several times in a row?Every download re-saves JPEG and WebP at quality 92, so save, reopen, rotate again stacks small losses. Do all the turns in one session, or save as PNG.
• I rotated my transparent logo at an angle and got white corners; how do I keep the background transparent?The white corners are background color filling the gap. Save as PNG or WebP and tick 'Transparent background instead of a color', because JPEG cannot hold transparency.
• What is the difference between flipping an image vertically and rotating it 180 degrees?A vertical flip mirrors the photo like a reflection in water, so text reads backwards; a 180 degree turn puts it upside down without mirroring. And when they cancel out.
• How do I mirror a design before printing it on heat transfer paper for T-shirts?Many transfer papers are pressed face down on the fabric, so the design must be mirrored first. Tick the horizontal flip and save as PNG to keep quality and transparency.
• Why does rotating a very large photo by a free angle fail on my phone?Expanding at a free angle makes the canvas bigger than the photo: 49 megapixels at 33 degrees becomes about 94, which can exceed a phone's memory. Here are the fixes.
• When I turn a square photo by 90 degrees, should I pick expand canvas or keep the original size?For a square photo at 90, 180 or 270 degrees both options give the same result, with no clipping and no gaps. The choice matters at free angles and on non-square photos.
• Can I rotate an image and convert it from PNG to JPG in the same step?Yes: pick JPEG under 'Save as' after rotating. Transparency is filled with the background color you choose, and quality is fixed at 92. When to use the converter instead.
• To turn a photo to the left, do I type 90, -90 or 270 degrees?Positive is clockwise, so left is -90. The angle field only accepts -180 to 180, so 270 is rejected, but the buttons fold your turns into that range for you.
• Is it fine to flip a product photo horizontally so it faces the other way in my layout?A horizontal flip is fine for symmetric products with no text, but it mirrors logos, labels, and the side of buttons and zips. When it is safe and when it misleads.
• I photographed invoices with my phone and some came out sideways; how do I fix them before combining them into a PDF?Turn each sideways photo 90 degrees until the text is upright, then combine the photos into a PDF. If the PDF already exists, rotate its pages in the PDF tool instead.
• How do I find my logo's color code to enter in my Salla or Zid store color settings?How to take the exact HEX code from your logo file and paste it into your Salla or Zid store color settings, and which logo file gives the truest value.
• Why is the color code I picked from an image slightly different from my official brand HEX?You picked a color from an image and the code is slightly off your official brand HEX. Where the drift comes from, when to ignore it, and when the file is the problem.
• Is a color code taken from a photo of fabric accurate enough to order the same shade from a supplier?A code from a fabric photo is exact for the photo, but the photo is not the fabric. How to use it with a supplier without a surprise shade in the shipment.
• Why does the picker warn me the pixel is transparent when I click on my PNG logo?Clicked your PNG logo and got a transparent pixel warning? What the opacity percent means, why the values there mislead, and where to click instead.
• Should I use the color picker or the palette extractor to pull brand colors out of an image?Two tools pull colors from an image in different ways: one exact pixel, or averages of color groups. When to use each, with a worked example in numbers.
• How do I collect the five colors in my logo and copy them all at once?Instead of copying each color separately, use the picker's color history: every click adds a color, repeats are not stored twice, and one copy gives you the whole list.
