Perplexity is built for questions with a factual or research angle: comparing specifications, checking a figure, finding out what an object or a document actually is. That makes image input a means rather than an end. You are not asking for a description, you are asking for a conclusion, and the clearer the input set, the less room there is for an answer that misses the point.

A grid turns scattered files into a single reference object. If your question is which of these three labels claims the highest capacity, the cells have to sit in the order your sentence implies. Separate uploads cannot guarantee that; one merged image can. When the pictures come from several sources, the same reasoning is set out in our combine images for AI pillar.

Cases where this pays off: (1) source checking, where a screenshot of a claim and a screenshot of the original document are merged so both appear in the same answer, (2) product comparison, where two or three specification tables go into the Strip of 3, (3) logistics or timetable questions, where several screenshots are merged in chronological order, (4) document questions, where the first page and the signature page of a contract are shown together.

Build it like this: drop the images into the cells in the order your question will name them, use 1×2 for a straight pair, the Strip of 3 for a sequence, or 2×2 for four items. Export at 2048px on the longest side so small print stays legible. An answer about a figure or a reference is only as good as the text you showed, and the free plan covers PNG or JPG output up to 4000px if you need more.

Then write the prompt in three parts: the layout, the content of each cell, and the question. For example: this is a row of three, left to right: January statement, February statement, March statement, which month shows the largest unexplained variation? That structure is what makes the answer checkable instead of merely plausible.

MergeFrame runs entirely in your browser, so a grid built from an unredacted statement or a contract page never leaves your device while you prepare it. The free plan covers 2 exports per day at up to 4000px, with 12 images per grid arriving six files at a time. The 24-hour Pass at $3 removes the daily export limit for 24 hours and adds PDF and WebP output.
