Image & PDF Compressor — ConvertorLab

Drop photos, screenshots, HEIC images or PDFs, choose compression mode (Soft/Balanced/Strong/Max) and optional resize. The tool never returns a bigger file — if recompression is larger, it keeps the original.

Upload & Settings
Add images or PDFs, pick mode, output, quality & resize, then hit Compress.

Drag & drop images or PDFs here

Supported: JPG, JPEG, PNG, WEBP, GIF, BMP, SVG, HEIC (decoded locally), PDF

Limits: max 200 files · max 1 GB total

Modes only control quality + resize. They do not change format. For PNG & graphics, choose WEBP/JPG output for real compression. For HEIC, the browser cannot write .heic, so images are decoded locally and saved as JPG/WEBP.
No files selected.
Files & Compression Results
Live thumbnails for images, HEIC and PDFs. Real size savings per file — never larger than original.

JPG/WEBP/HEIC photos are recompressed with your mode and quality, with optional downscale. PNG/GIF/BMP/SVG stay untouched in "Keep format" mode to avoid bigger files — convert to JPG/WEBP for real compression. PDFs are re-saved with structural optimizations and never returned larger than the original.

About Image Formats, Size and Resolution

Modern image formats like JPG image, PNG image, and web-friendly web JPG are great for sharing, but high-resolution camera shots can create very large files. Large jpg file images and png files quickly slow down websites and fill cloud storage, especially when you never reduce image file size online or adjust image resolution.

This tool focuses on reducing image resolution only when needed, then tightening compression so your img compressed results still look like quality images. You can use it as a jpg image converter, pair it with other online image converter tools (like image to PNG or image to image conversions), or simply treat it as a jpg file online compressor when you only want to shrink file size.

While this is not a full compression GIF engine, you can still optimize web images before placing them next to animated elements, ensuring your pages stay fast even with rich visual content.
