Bulk image resizer
Resize a whole folder of images at once, with no file limit.
Drop your file here
It is processed on your device — nothing is uploaded.
A folder at a time
Drop in up to two hundred images, set the size once, and get them all back as a zip. Every file gets the same treatment, and the originals are untouched.
Why there is no daily limit
Because there is no server. The work happens on your own processor, so processing two hundred images costs us exactly nothing — which is why there is no cap, no account and no queue.
The tools that ration this do so because each image costs them money. TinyPNG stops at twenty files for that reason. It is a business constraint rather than a technical one.
Choosing the mode carefully
This matters more in a batch than for one image, because you will not be checking each result.
Fit is the safe default: nothing is cropped and nothing is distorted, and images of mixed orientations all end up within the box.
Fill crops to exact dimensions, which is right for thumbnails and wrong for a mixed batch — a portrait photo cropped to a landscape frame loses the top and bottom of the subject.
Percentage scales everything by the same factor, which preserves the relative sizes across a set. Often the right answer for a folder of camera files that just need to be smaller.
Check one first
Run a single image through the single-image resizer with the settings you plan to use. Two hundred images with the wrong mode is two hundred images to redo.
Memory
Every image is decoded to work on, so a very large batch of very large files can exhaust a phone. Split it in half if it struggles — it costs nothing to run twice.
Common questions
How many images at once?
Up to two hundred, limited mainly by your device memory.
Why is there no daily limit?
The work happens on your processor, so it costs us nothing. Sites that ration this pay per image.
Which mode for a mixed batch?
Fit. Fill crops to exact dimensions, which mangles portrait photos in a landscape frame.
Should I test first?
Yes — run one image through the single resizer. Two hundred wrong results is two hundred to redo.
Are the originals changed?
No. You get a zip of new files.
