How to Stretch Multiple Images at Once
A folder of shots that all have to hit the same box does not need twenty separate downloads — drop up to 20 files, set one size, and save a ZIP in the browser.
A listing grid, a week of stories, a stack of scans headed for the same sheet: the destination is one box, and you already like the pictures. Opening each file, typing the same width and height, and hitting Download twenty times is the slow version of that job. Stretching multiple images at once is the same remap, shared across a queue, then one ZIP.
The batch stretch images page on ImageStretcher opens already in Batch. Home can do it too — tap Batch, or open a link with mode=batch — but the dedicated page is the walkthrough below. Stretch and ZIP stay on the device. No account.
What “one size for the set” actually does
The queue shares the output box. A tall product shot and a wide banner both land on the width and height you set. That is the point when a catalog tile or a story slot has to match. It is the wrong move when two files need different boxes — then Single is faster than fighting the shared controls.
Crop and Replace still hit only the selected frame in the filmstrip. The size, aspect lock, template, and export format apply to everyone. Share link is off in Batch on purpose: a public copy is a separate, explicit tap on Single, not something a ZIP workflow should do by accident.
Stretch a set in the browser
Desktop has a drop zone. On a phone, the picker is the path — same as Single, just with multiple files allowed.
- Open batch stretch images. The tool is already in Batch.
- Drop up to 20 JPG, PNG, or WebP files. The strip under the preview is the queue: tap to select, tap × to remove, tap + to add more.
- Set the box once. Select Template if the slot already has a name; otherwise type width and height, or lock an aspect and let one side follow.
- Flip through the strip. A mild pull that looks fine on a landscape still can pinch a portrait once you select it.
- Tap Download ZIP. Files keep their original stems plus a timestamp, packed as
imagestretcherIO-plus local time.
Leave Target File Size empty unless the slot also has a KB cap. JPEG and WebP still have a quality slider; PNG keeps hard edges. Paste and URL upload still add one image at a time — useful for a missing file, not for the whole folder.
Twenty is the cap. Download the first ZIP, then drop the next set. There is no server queue sitting on a folder overnight.
When Batch is the wrong first tap
One hero image you are still deciding how far to pull belongs in Single. Faces, logos, and UI chrome that cannot warp still want crop before any stretch, and that crop is per selected frame, not a gift to the rest of the queue. A file-size limit with no new shape is compress image, which can follow the ZIP or run on its own.
Camera-roll shots are still photos. The photo stretcher is the same canvas when the brief is one camera still; this page is the folder version of that remap.
A set that must fill a named social box without cropping each edge off is a stretch job — how to stretch an image for social media names the slots; Batch is how the folder gets there in one pass.
