The whole album,
in one pass.
Resize and compress dozens of photos at once — cap the long edge or scale by percentage — then grab everything as a single ZIP. All local, no batch limits.
How do I resize many photos at once? Select the batch, pick "max long edge" (1600 px is the web-friendly default) or a percentage, choose JPG/WebP, and process. Download the results as one ZIP — everything runs in your browser, nothing is uploaded.
Bulk image resizer
Images already smaller than the target are left at their original size (no upscaling). Transparency is flattened onto white for JPG output; keep PNG or WebP to preserve it. Single files? The target-size compressor hits exact KB limits.
How to bulk resize photos
- Select the batch — a folder of phone shots, product photos, or event pictures.
- Pick the rule — "max long edge 1600 px" is the web/email sweet spot; 50% halves everything; 2048 px suits large screens.
- Resize all, then grab the ZIP — each file shows its before → after size; download individually or all at once.
What "max long edge" actually does
Every image keeps its aspect ratio; only the longest side is capped. A 4032×3024 iPhone photo at 1600 becomes 1600×1200 — under a megabyte, still crisp on any screen. Portrait and landscape mixes in one batch work fine because the rule applies per image, not per batch. And images already below the target pass through untouched — this tool never upscales (that's Image Upscaler's honest job).
Good to know
WebP typically lands 25–35% smaller than JPG at the same look — if the destination is a modern website, it's the better default. The ZIP is built in your browser with the same engine used by the ZIP tool, and a batch of thirty photos finishes in seconds because nothing uploads. Photos with GPS or camera metadata? Resizing through the canvas strips it along the way — for full control of that, the EXIF viewer shows what's inside and cleans a copy.
How do I resize many photos at once?
Select the whole batch, pick a rule (max long edge or a percentage), choose the output format, and process. Every photo is resized locally in your browser, and you download the results as a single ZIP.
Is there a file count or size limit?
No server limits — the work happens on your device, so the practical ceiling is your browser's memory. Batches of dozens of phone photos work comfortably on a laptop.
What does 'max long edge' mean?
The longest side of each image is capped at your number, keeping the aspect ratio. A 4032×3024 phone photo at 1600 becomes 1600×1200 — perfect for web or email, still sharp on any screen.
Are my photos uploaded?
No. Everything — resizing, compression, and the ZIP — is built in your browser tab. Batch jobs with private photos are exactly what this is for.
