Two new free tools: an image format converter and a video-to-GIF converter
Alongside the App Store screenshot editor, the icon generator and the QR code generator, Ecranify now has two more free tools: an image format converter and a video-to-GIF converter. Both are free, need no signup, and live at ecranify.com/tools with the rest.
Neither is a toy demo bolted onto the site — the image converter has a real interactive preview (its own drop zone, a live simulation of JPEG/WebP compression as you drag the quality slider, a crop tool, an exact output-size estimate) and the video converter runs the actual conversion on a server rather than in your browser, so a long clip on an old phone converts as reliably as a short one on a desktop.
Image converter: which format actually fits your use case
PNG, JPEG, WebP, GIF, BMP and ICO all solve slightly different problems, and picking the wrong one is a common, avoidable source of bloated page weight or missing transparency. The converter handles all six, both directions, entirely in the browser — nothing is uploaded anywhere.
- PNG — lossless, supports transparency. Use it for logos, icons, screenshots with UI chrome, or anything that gets edited again later.
- JPEG — lossy, no transparency, smallest files for photos. Use it for photographic content where a little compression is invisible but file size matters (email attachments, photo galleries).
- WebP — modern, usually smaller than both PNG and JPEG at the same visual quality, with optional transparency. The right default for web images if you don’t need maximum compatibility with very old software.
- BMP — uncompressed, large, universally readable by the oldest software. Rarely the right choice today; mostly needed for legacy tooling or Windows-specific workflows that expect it.
- ICO — the Windows icon container format, supports several sizes in one file. Needed specifically for Windows app/favicon icons; not a general-purpose image format.
A preview that actually shows you the result
Dragging the quality slider on a JPEG or WebP export re-encodes the image through the real browser codec and redraws the decoded result — so what you see is what you get, compression artifacts included, not a flat draw that ignores the slider. An exact output file size is computed the same way, from the real encoder, not a guess.
The preview is also a drop zone in its own right, and includes a crop ("trim") tool with draggable corner handles for cutting an image down before converting it — useful for stripping unwanted borders or focusing on one part of a larger source image without leaving the tool.
Video to GIF: why GIF still matters in 2026
A GIF autoplays everywhere a video usually can’t — inline in a Slack message, a forum post, a README, a tweet, an email — with no player controls, no tap-to-play, no format-compatibility question. That single property (silent, looping, autoplaying, universally supported) is why short-form clips still get converted to GIF constantly, video codecs aside.
Upload a clip, pick a start and end point, choose a resolution and frame rate, and the conversion runs server-side with a real ffmpeg encode — including the standard two-pass palette-generation technique that keeps a converted GIF from banding or looking muddy, which a naive conversion skips.
Where these fit if you’re shipping an app
Both tools are useful well outside app marketing, but they line up with it too: convert a design export between formats before it goes into an App Store listing, turn your app icon source art into the exact ICO a Windows build needs, or clip a short screen recording into a GIF preview for a landing page, changelog or investor update — something an App Store screenshot preset isn’t built for, and a full video export is overkill for.
