Emails bounce when attachments are too big (Gmail allows 25 MB, Outlook 20 MB), and large photos are slow to send on WhatsApp. Choose your files and a target size: each photo is reduced to fit under it with the best quality possible, and other files are packed into a compressed ZIP. Nothing is uploaded, so it is safe for ID documents, contracts and private photos.
How to use
- Choose one or more files. Photos and documents can be mixed.
- Pick a target size per photo, or enter your own.
- Press Compress, then download each photo or everything as one ZIP.

Frequently asked questions
What size limits do email and WhatsApp have?
Gmail allows 25 MB of attachments per email and Outlook 20 MB. WhatsApp sends documents up to 2 GB, but photos and videos up to 16 MB, and smaller files send much faster on mobile data.
Why did my PDF or Word file barely shrink?
PDF, DOCX, XLSX, JPG and MP4 files are already compressed inside, so zipping them saves little. Text files, CSV, BMP, TIFF and uncompressed data shrink a lot.
Will the photos still look good?
The tool keeps the highest quality that fits your target and only reduces the dimensions when quality alone is not enough. 1 MB is plenty for a sharp photo on any phone screen.
