What you get without a plan
No login between the photos and the ZIP
Carousel sites often preview one frame, then demand email to download the rest. This spoke is the opposite: switch to Carousel, set a ratio, export. Shared family computers and classroom Chromebooks can finish a pack without a new password. Being signed in for other Convertify4u tools does not change the filmstrip pipeline. If a site-wide banner invites you to log in, you can ignore it and still Save All.
Pixels versus the download name
We do not overprint a logo on each slide. Free-tier helper code may insert convertify4u into a filename stem. Unzip, rename slide-01.jpg to whatever the brief says, and inspect the image — there is no baked banner. Paid/unlimited users skip the suffix. That is the only “upgrade” that touches this tool, and it is cosmetic on the name, not on the bitmap.
Ceilings we will not advertise as unlimited
Sixteen slides. Three aspect boxes. Capture at 2× CSS size. JPEG/PNG/WebP/GIF in. No generative fill. Those limits are why the path can stay free and local: your device does the slice. If you need a 40-frame course with branded type on every card, you are in a deck tool. If you need a ten-frame Instagram walk from photos already on disk, this is the whole product.
