6 Best Free TinyPNG Alternatives to Compress Images (2026)
TinyPNG caps file count and size on its free tool. Here are free alternatives that compress without the limits.
TinyPNG is a classic for shrinking PNGs and JPGs — but the free web tool caps how many files and how large you can compress before nudging you to a paid plan. If you compress images regularly, here are the best free TinyPNG alternatives in 2026 that don't fence you in.
Where TinyPNG's free tier stops
The free TinyPNG web tool limits batch size and per-file size, and heavier or bulk work pushes you toward the paid API or a subscription. For occasional single images it's fine; for volume, you want a tool without the ceiling.
1. sjpt.io — compress to an exact size, free
sjpt.io compresses JPG, PNG and WebP with no file-count limit, no sign-up and no watermark, and lets you drag a quality slider to hit a target size (say 100 KB). It runs in your browser, so images aren't uploaded. Full comparison at sjpt.io/alternatives/tinypng-alternative.
2–6. Other free compressors
Squoosh (by Google) — excellent visual quality control, one image at a time. Compressor.io — good results, some formats gated. iLoveIMG — batch-friendly but has daily limits and upsells. ShortPixel — strong compression with a monthly free credit cap. Each is useful; the trade-offs are batch limits and sign-up walls.
Lossy vs lossless — quick primer
Lossless (what TinyPNG is known for) reduces size without discarding visible detail — best for logos and screenshots. Lossy squeezes further by dropping detail you're unlikely to notice — best for photos. A good alternative lets *you* choose the balance with a slider instead of guessing.
How to compress an image free
Step 1 — Open sjpt.io/compress-image.Step 2 — Upload your photo.Step 3 — Drag the quality slider until the estimated size hits your target.
Step 4 — Download the smaller file — no watermark, no limit.
