Batch convert
Batch convert writes every dropped image to one target format. Camera-roll HEIC to JPEG, a pile of PNG screenshots to WebP. Spot-check one file on the single converter first if the format is lossy.

About Batch Operations
Single-file tools are for looking. Batch is for when you already know the settings and you have a folder. Each of these pages takes many files, does the same job to each, and hands you a zip. Your laptop will get warm. That's the trade for not sending the folder to someone else's disk.
There's no cloud queue and no “we'll email you when it's done.” If the tab stays open, the work continues. If you close it, it's gone, there was never a server copy to resume.
Rename only changes names inside the zip. It doesn't touch the originals on disk. Strip EXIF the same way: new files in the zip, originals left alone.
Tools in this category
Batch compress
Batch compress re-encodes many images to JPEG in one pass. Same quality for all. If some shots are already small and some are huge, you may want two passes rather than one aggressive setting.
Batch watermark
Batch watermark stamps the same text on every file. Proofs, agency name, a date. Position and opacity are shared. If one image has the subject in the corner where the stamp lands, that's on you, look at a sample.
Batch rename
Batch rename applies a pattern (prefix, index, original name) and zips the result. Useful before a handoff. It won't reorganize your disk; it only names what goes in the zip.
Batch EXIF strip
Batch EXIF strip removes metadata from many files at once. Same warning as the single stripper: headers go, pixels stay. For a folder of phone photos headed to a client portal, this is the one I actually run.
Common questions
How is batch convert different from the single converters?
Same kind of encode, many files, zip out. The single pages show a preview so you can judge quality. Batch assumes you already know. If you don't, convert one image first.
What do I download, one file or a zip?
A zip of the results. Browsers don't have a good “save this folder” API, and I'm not going to download forty files one click at a time on your behalf.
Will batch EXIF strip also recompress my photos?
It writes new files without the metadata. Depending on format, that can mean a re-encode. If you need bit-identical pixels plus no tags, test one file and compare. For JPEG, “strip” and “byte identical” aren't always the same sentence.
Why these tools don't upload your files
There is no server to upload to. Each page is a static file, and the work happens in your browser. Your file is read from disk into memory, processed, and handed back as a download. Once the page has loaded you can disconnect from the network and it keeps working. The longer explanation
